Prone Bone Sex Position: How It Works, Benefits & Tips

Ever heard of the prone bone sex position? It’s one of those trending twists on doggy-style that’s easy to try and surprisingly cozy. Picture this: one partner lies face-down (prone) on the bed, while the other partner mounts from behind. In other words, you’re essentially flattening out a classic rear-entry move. The name says it all – “prone” (lying face-down) plus “bone” (slang for sex) – so you’re “boning” someone while you’re prone on your stomach.

In sex advice lingo, prone bone is sometimes even called the Flatiron Position or Spread Eagle, because the receiving partner lies almost completely flat with hips slightly lifted. It’s also known informally as “flat doggy style,” since it’s like a level, full-body version of regular doggy. Anatomically, being prone just means face-down, and indeed, the receiving partner in a prone bone lays flat on their belly. The other partner then comes up behind and penetrates from the rear.

This guide will explain exactly what the prone bone position is, how to do it, and why couples might love it. We’ll cover the advantages (spoiler: comfort!), differences from classic doggy style, cool variations, and tips for making it work for any body type. Along the way, we’ll answer common questions like “What does prone bone mean?”, “How does it differ from doggy style?”, and even “What does it mean when a girl ‘bones’ a guy?”. (Hint: it’s just slang for “having sex.”) We’ll even suggest some fun Leather Impressions products like leather pillows and swings to spice things up. So let’s roll over into the details!

What is Prone Bone Sex Position?

At its core, the prone bone position is exactly what it sounds like: sex while prone. One partner (the receiving partner) lies face down on their stomach, body fully supported by the bed or floor. The other partner (the penetrating partner) lies on top or kneels behind and enters from the rear. Because the bottom person’s body is completely flat (like lying face-down), the position is a version of “flat doggy style.”

One sex therapist even calls it the Flatiron position. In that article, the therapist notes that “the Flatiron Position, also known as the Prone Bone or Spread Eagle, offers a different perspective on intimacy”. In short, it’s a slight rebranding of the same move – but the name “prone bone” seems to have caught on as a fun slang term.

So what does prone bone mean?

It’s slang for having sex while one person is lying face-down. According to one slang dictionary, “Prone Bone” is a slang term for a sexual position in which one partner lies on their stomach and the other mounts and inserts from behind. (In even plainer words: you “bone” while you’re “prone.”)

You might wonder what a “prone position” is in general. In anatomy, “prone” just means the body is flat with chest down, back up. It’s the opposite of lying on your back (supine). So a “prone position” just means face-down. The prone bone sex move takes that literally – you lie fully on your front.

Some couples call it “flat doggy” or even just “the flatiron” because of the straight, flat posture of the receiving partner. Others jokingly compare it to baking a pizza (dough flat, sauce on top)! Whatever you call it, the key is that the bottom person is flat on their stomach, which changes the angle and feel compared to regular doggy.

Other Names and Synonyms

• Flatiron/Flat Iron Position: A name used by some therapists and bloggers for prone bone.
  

• Spread Eagle: Another nickname for a fully flattened position.
  

• Flat Doggy Style: Informal way to describe it (“doggy style, but flat on the bed”).
  

No matter what term you hear, it’s the same basic idea. A Houston therapist’s blog confirms “the Flatiron Position, also known as the Prone Bone or Spread Eagle”, so all these names refer to lying flat with rear-entry.

How to Do the Prone Bone Position

Getting into prone bone is pretty straightforward, but little adjustments make it more comfortable and pleasurable. Here’s a step-by-step breakdown:

1. Receiving Partner Lies Face-Down: The person being penetrated lies flat on their stomach. Arms can be by the sides, under the head, or even hugging a pillow – find a comfortable position so your chest and belly are supported. It’s often best to keep legs together and straight, or slightly apart if that feels better.
   

2. Support with Pillows (Optional): To improve the angle, try sliding a pillow under the hips or pelvis. This tilts the hips up slightly and can make penetration easier. Experts note that “a pillow under the hips is your best mate here – it helps with comfort and angle”. You can also place a cushion under the chest or forehead for support so breathing isn’t restricted.
   

3. Partner Aligns Behind: The other partner kneels or leans over from behind. If on a bed, kneeling behind the prone partner works well. If the bed is high, sometimes the person behind can stand (the therapist guide even mentions the penetrating partner may kneel or stand behind if the receiving partner is on an elevated surface). The goal is that your pelvises line up.
   

4. Enter Carefully: The partner behind gently guides into the receptive partner’s backside or vagina. Because the bottom partner is flat, this can feel shallower at first. Take it slow and let your bodies adjust. The receiving partner can move hips or raise pelvis slightly to encourage deeper entry.
   

5. Adjust Arm Positions: The prone person can prop on elbows (like a swimmer’s position) if they want to lift the chest off the bed. Or they can keep arms down by the sides or reach forward onto a pillow. The partner behind can hold the bottom’s hips or waist for stability.
   

6. Find Your Rhythm: Once positioned, begin thrusting slowly and build up rhythm. Communicate – if the angle isn’t quite right, shift positions or add more pillows. The most important part is that both partners feel comfortable.
   

In short: Prone bone is basically “the other person lies down flat, you enter from behind.” A good article describes it as “the receiving partner lying face down with their hips slightly elevated... the penetrating partner kneels or stands behind, penetrating from the rear”. You can adjust the angle with pillows and play with how much body weight or pressure the partner on top puts on the bottom’s back.

Tip: A common setup is for the bottom partner to rest on forearms (elbows under shoulders) to keep the spine fairly straight. This makes breathing easier and lets the upper body relax. If that feels hard, rolling onto your side or propping on pillows is fine too.

Quick How-To Steps

• Step 1: Lie flat on your stomach. Keep your spine neutral and legs together (or comfortably apart).
  

• Step 2: Slide a cushion under your hips to tilt them up if it helps.
  

• Step 3: The other partner comes up behind you. They line their pelvis against yours from behind (kneeling or standing).
  

• Step 4: Slowly enter. Communicate depth and angle.
  

• Step 5: Adjust as needed – speed up, slow down, change angles, and enjoy!
  

These steps cover “how to prone bone”. Once you’re in, experiment with depth and speed. You might need to shift a bit – for instance, the receiving partner can inch forward until the base of the spine starts to lift, allowing deeper entry. The person on top can lean closer to give more pressure or hold back a bit for a softer feel.

A quick note: because both bodies are parallel, you’ll feel a lot of skin-to-skin contact and close body warmth. It’s a very “full-body” sensation. One thumbs-up from a casual survey of couples is that it feels cozy – like spooning but with the spine aligned.

Benefits of the Prone Bone Position

Why try prone bone? It has some nice advantages:

• Full Support & Comfort: Since the receiving partner is lying flat, their weight is fully supported by the bed. Unlike doggy (which can strain knees, shoulders, or lower back), prone bone lets the bottom relax completely. Many people find it very comfortable for this reason. A kissing-couch-to-bed translation: “Just lie there and enjoy” is literally what you can do.
  

• Great Angle for Stimulation: With your hips slightly tilted up by a pillow, the angle can allow deep penetration. Experts note that the Flatiron/Prone Bone position “allows for deep penetration and enhanced physical connection”. This can stimulate G-spot or P-spot regions more effectively for some couples. It’s not just shallow – with a good tilt, it can be intense.
  

• Versatility (Vaginal or Anal): Because of the body alignment, prone bone works well for both vaginal and anal sex. The same Houston therapist article points out it’s good for either type – “the Flatiron… allows for deep penetration”. Similarly, a popularity report noted “If you like doggy style, you’ll love this. … it’s great for vaginal or anal orgasms”. So it’s a versatile entry position for lots of different activities.
  

• Less Strain on Arms/Back: The person doing the penetrating can also benefit. When you’re kneeling or leaning over, you can use your hands on your partner’s hips or the bed for support, and gravity helps press you forward. You’re not having to bear much weight on shoulders or knees – it can feel more relaxing. Likewise, the bottom partner doesn’t have to “hold themselves up” at all.
  

• Intimate Contact: Prone bone is pretty intimate in a different way. The bodies are flush together, torso to torso, which means lots of skin contact. You can even whisper, stroke, or play with the other partner’s body (their back, hips, legs) while you move together. It’s not face-to-face contact like missionary, but it’s very “close” in its way. If you press your ear back against your partner’s shoulder, you can feel each breath – it can be quite sensual.
  

• Easy Breathing: Many people find it easier to breathe in prone bone. Because your face is free (not smushed into a pillow like in doggy), the receiving partner can lie fully flat with head turned or raised slightly. This means you won’t feel like you’re suffocating on the mattress.
  

• Great for Mid-Pace or Lazy Days: Prone bone feels somewhat effortless. It’s a good position for when you want to take it slow and relax together. You’re not up on elbows pushing or flipping around – just steady motions. That makes it a good “lazy day” position, or when you want to focus on feeling rather than moving crazy.
  

• Pillow-Enhanced Comfort: Many guides stress using cushions. One sex column quipped that “a pillow under the hips is your best mate here” for added comfort and better angle. One big perk is that you can use support props easily, and it pays off. Even your favorite leather or bondage pillow can make it cozier.
  

In short, the prone bone position combines comfort with versatility. It’s a simple tweak from doggy-style that can spice things up without needing to twist yourself into a pretzel.

Example: One real-life couple said they love prone bone when one of them is feeling tired – the bottom partner just relaxes flat while the top partner does all the work. It’s “easy on the body” but still intimate. They also noticed the extra skin-on-skin heat cranks up the feeling.

Prone Bone vs. Doggy Style: What’s the Difference?

Prone bone is often compared to classic doggy style, so let’s highlight the differences:

• Body Position: In regular doggy style, the receiving partner is on all fours (hands and knees, butt up). In prone bone, the bottom partner is completely flat on their stomach. Imagine taking the arch out of doggy so that the back and legs are flat – that’s prone bone.
  

• Angle of Entry: Doggy style typically points the hips upward at a steeper angle (especially if the bottom partner’s knees are tucked). Prone bone, with the belly on the bed, is a shallower angle. This can change what spots are stimulated. For some, doggy gives a harder angle to the cervix; prone allows more full-surface contact. You can adjust with pillows under hips – we say it’s like leveling the doggy.
  

• Contact Surface: In doggy, only the knees, hips, and chest touch the ground, with an arch. In prone bone, the entire front torso (chest down to legs) is on the bed. This means more surface-to-surface heat and less “free movement” of the bottom’s body. It can feel snugger.
  

• Strain and Effort: Many find prone bone less physically demanding on both partners. Doggy can cause shaky arms/wrists for the bottom or burning in the legs at the top. Prone bone spreads your weight out. The Houston therapist article remarks that the top partner can even stand instead of kneeling if needed (for comfort).
  

• Intensity: Some people say doggy style feels more intense at times because of the sharper angle, while prone bone feels smoother. However, with the right adjustments (like a cushion under hips), prone bone can feel just as deep. It’s largely a matter of preference. A sex trend report even suggests, “If you like doggy style, you’ll love this [prone bone]” – meaning they feel similar enough that doggy enthusiasts enjoy flat doggy too.
  

• Visual/Aesthetic: In doggy, partners usually face the bed or a headboard, whereas in prone bone, you’re more face-to-face horizontally or looking off to one side. It’s a slightly more eye-to-back view (unless you both lie neck-turned to see each other). So if you love watching each other’s faces or reacting, Doggy might have the edge. But prone bone still allows the partners to touch and feel each other’s bodies fully.
  

• Variations: Doggy has well-known variations (doggy from standing, doggy with pillows). Prone bone itself has its twists (see next section), but by definition it remains flat-based.
  

Bottom line: Prone bone is just a flattened doggy-style. It’s the same “rear-entry” vibe but with the receiving partner’s body horizontal. This slight change yields a different sensation: more uniform pressure and support. It’s worth trying if you like doggy but want something easier on the arms/back or just a new angle. As one source put it, prone bone “is like doggy but simpler” – you lie flat and let gravity do some work.

Variations

Like any position, there are creative tweaks to keep prone bone interesting. Here are some popular variations and ideas:

• Pillow Variations: The simplest tweak is swapping different cushions. You might start with a pillow under the hips, then add one under the chest if you want even more tilt. Or prop the receiving partner on a rolled-up blanket or yoga bolster. Changing pillow placement alters the penetration angle.
  

• Leg Positions: Experiment with leg stance. Often partners keep legs together for a solid “platform.” But you can try knees apart, even a half-split, to let the giver move between legs easily. Or have the bottom partner lift one leg (like resting a foot on their partner’s shoulder) for a one-leg variation.
  

• Arm Positions: Change how the bottom partner uses their arms. One variation is to let the receiving partner rest fully on one side (like lying half-prone) so one shoulder lifts, exposing a slightly different angle. Another is to have them stack both arms under their head (like in a relaxed swimmer’s pose), so only chest and legs touch the bed.
  

• Supports and Restraints: Incorporate a sex swing or bondage harness. For instance, using a leather sex swing (with loops for legs and a chest pad) can lift both partners slightly and allow motion without kneeling. A swing makes it easier for smaller partners to reach bigger ones, or vice versa. Similarly, gentle wrist restraints (like padded cuffs) can be added to keep hands neatly behind or to invite some kink. The Leather Impressions sells high-quality leather swings and pillows that can add fun support to this move.
  

• Edge-of-Bed Prone: Try prone bone at the edge of a bed. The receiving partner lies on the bed’s surface, but their hips extend slightly off the edge (with legs on bed). The giving partner stands or kneels on the floor. This change in level can let the standing partner thrust more easily, and give a different leverage.
  

• Suspended Variation: For adventurous couples, loop your legs through a nearby sturdy bar or even utilize a standing pole (like in a dance class). The receiving partner stays face-down, but their ankles or legs are supported. The top partner can then pick up the hips more drastically. (Only try safe setups and communication!)
  

• Alternating Center of Gravity: As the name suggests, “flatiron,” you can rock your hips from side to side (like ironing back and forth) instead of just in-out thrusting. This gentle swaying motion can stimulate the sides of the pelvis.
  

• From a Chair or Couch: If you’ve got a leather chair or couch handy, you can bend over it in a flat position and have your partner enter from behind. This keeps the body flat but changes the support structure (kind of like a bed is a chair).
  

As one sex guide puts it, “just like any sexual position, the Flatiron allows for variations” – they suggest experimenting with “different angles, speeds, and depths”. In practice, that means adjusting how flat or tilted you are, going slow or fast, thrusting shallow or deep, and finding what drives you both wild. The possibilities are limited only by your creativity and comfort.

Tips for Different Body Types

Every couple’s body proportions and flexibility are different, so here are some practical tweaks to make prone bone work for you:

• Support for Every Size: If you or your partner is on the curvy/heavier side, using cushions is crucial. Place a firm pillow under your hips and even one under the belly if needed. This prevents any pinch in the lower back. The Leather Impressions bondage pillow or a leather-covered cushion can be both supportive and sexy looking! For smaller-framed bottoms, you might need less pillow—just enough to lift the pelvis an inch or two for clearance.
  

• Height Mismatch: When one partner is much taller, alignment can be tricky. If the top partner is taller, try doing prone bone on a low bed or even a floor mattress so they don’t bend down so far. If the top partner is shorter, have them kneel on a small step stool so their hips align with the bottom partner’s hips. Conversely, the bottom partner can rest on a raised platform (like the edge of a couch) to even things out.
  

• Plus-Size Comfort: Lie on a sturdy surface (firm mattress or floor) so you feel fully supported. Keep your legs together and maybe slightly bent to take stress off the lower back. The top partner can adjust posture (kneeling vs standing) to avoid putting too much pressure on the bottom partner’s torso. Remember, more pillows = more comfort.
  

• Flexibility & Flex: Don’t force anything. If you have knee or wrist issues, prone bone is already easier because no crawling around is needed. But if the bottom partner has tight hips, they can spread their legs wider to ease tension. If the top partner has back sensitivity, support their weight on forearms or a backrest.
  

• Pregnancy/Pelvic Concerns: If someone is pregnant or has a sensitive belly, try the flatiron variation on their side instead of fully prone. Or lie on your stomach with a gap (use a big belly pillow or wedges so the belly isn’t compressed), letting the partner reach in. Always avoid putting pressure on the belly.
  

• Leverage with Leather Gear: For unique body dynamics, use tools. For instance, if your partner has weak legs, a leather sex swing with a supportive pillow (like the one sold by The Leather Impressions) can hold you up so you both only need to move your hips. That leather gear provides both leverage and comfort – freeing you from worrying about balance. (It also looks cool!)
  

• Communication is Key: Whatever your bodies, talk about what feels good or strained. Small shifts (like sliding a hand under a hip, or asking the top partner to lean more or less) can make a world of difference. And make sure to check in: “How’s my back? Am I too flat?”
  

Remember, there’s no single “right body” for prone bone. With pillows, props, and a bit of creativity, pretty much any pair can find a comfortable version. The idea is to have fun exploring it, not to match some impossible posture.

Common Questions

To make sure we cover all the bases, here are answers to frequent questions about prone bone:

What is the prone bone sex position?

 Prone bone is a rear-entry sex position where the receiving partner lies prone (face-down) and the other partner enters from behind. It’s essentially doggy-style with the receiver’s body flat on the bed. Think of it as flat doggy, flat on the stomach.

What does prone bone mean?

 It’s slang combining “prone” (lying on your stomach) and “bone” (slang for having sex). So it means “having sex while lying face-down.” A slang dictionary defines it as “a sexual position in which one partner lays on their stomach and the other mounts and inserts from behind”.

What is meant by a prone position?

 In general anatomy terms, a prone position means lying flat with your chest down and back up. So if someone says “prone position,” they’re just saying “face down.” In sex talk, this clarifies that the bottom partner is on their belly.

What is another name for prone bone?

 It’s often called Flatiron or Spread Eagle. Some people say “flat doggy” too. In Japanese slang, it’s known as “nebacku” (寝バック), which means “prone bone.” But whatever you call it, they all describe the same flat-down rear-entry pose.

What are the advantages of prone bone position?

Prone bone is prized for being comfortable and versatile. Because you’re lying flat, the pressure is evenly spread out, so it’s easier to hold and less tiring than some poses. It allows deep angles, so you can target the G-spot or cervix well. It works great for both vaginal and anal sex. You get lots of skin contact and a different sensation. As one sex writer puts it, this move “allows for deep penetration and enhanced physical connection”, and even recommends pillows for extra comfort.

How does prone bone differ from doggy style?

The main difference is posture. In doggy style, the bottom person is on hands-and-knees; in prone position, they’re completely flat on their belly. This changes the entry angle and how the pressure is felt. Doggystyle often feels more angled and intense, whereas prone bone feels more supported and can be gentler. A sexuality expert notes that if you enjoy doggy, you’ll often love prone bone too – just remember you’re lying flat instead of up on all fours.

Are there variations of the prone bone position?

Absolutely. You can tweak it in many ways: use pillows to prop different parts of the body, change leg positions, or even use furniture and gear. For example, adding a cushion under the hips or chest tilts your pelvis. You can spread your knees wider or lift one leg. Some people try it on the edge of the bed or with a sex swing for support. The Flatiron/Prone Bone position is known for allowing “different angles, speeds, and depths” – so play around and see what feels best!

How do you prone bone?

To “prone bone” simply means to take the prone position and have sex. It involves the steps we outlined: the bottom partner lies flat on their stomach (with maybe a pillow under their hips), and the other partner enters from behind. It’s an easy move once you get the hang of positioning.

What does it mean when a girl “bones” a guy?

This is slang. To say someone “bones” another means they’re having intercourse. So “girl bones a guy” just means the girl is having sex with the guy (she’s the active partner in that context). It doesn’t refer to any specific position in this usage – just a coarse way of saying “she screwed him.” It’s not a special move; it’s just someone’s way of saying someone is getting laid.

Final Thoughts

The prone bone sex position is a laid-back (literally!) way to switch up rear-entry action. It’s one of those moves that’s easy to try, doesn’t require crazy flexibility, and can be super satisfying. Because of the full-body support and easy angle, many couples find they can enjoy longer sessions without getting tired. It’s perfect for lazy mornings in bed or when you just want to relax and let your partner take the lead.

Like any position, communication is key: check in with each other about comfort and depth. Use pillows or a leather cushion to prop your hips at the right height. You might even slip into a leather sex swing to let gravity assist. The Leather Impressions swing with a comfort pillow is explicitly designed for moves like this. Small adjustments (tilting your pelvis, changing leg positions, altering pace) can make the position feel completely different.

And if you’re feeling adventurous beyond prone bone, don’t forget to explore other positions. For an ultra-intimate face-to-face vibe, try the Close Breathing Sex Position. If you want crazy depth and a workout, experiment with the Apex Sex Position. Or if you’re in the mood for some power-play, the Captain Sex Position adds a commanding twist to missionary. Each brings its thrill, so your bedroom repertoire stays fresh.

Above all, have fun with it! The prone bone position shows that sometimes the simplest twist on a classic can open up a whole new world of pleasure. Try it on a soft mattress, grab some pillows (or that sexy leather bondage pillow), and enjoy the ride. As always, go at your own pace and keep it consensual and playful.

Happy flat-out boning!
