The Anvil Sex Position: How to Go Deeper Without Losing the Slow Burn

She is already on her back, breath gone shallow, when you reach for her ankles and guide her knees up toward her chest. The whole room shifts. Her hips tilt up to meet you, the angle steepens, and suddenly there is nowhere left to hide. That is the anvil. One small change to a position you already know, and every stroke lands deeper than you thought it could.

Most couples stumble onto the anvil by accident and then spend months trying to find it again. Too much force too soon and it feels like a wall. Slow it down, prop her hips, and hold her gaze, and it becomes deep, unhurried pleasure. Couples often tell us they do not want more positions, they want a few that actually hit. Here is how to make this one of them, plus the one mistake that makes most people give up on it too early.

The anvil is a deep-penetration variation of missionary where the receiving partner lies on their back and raises both legs toward their chest, or drapes them over the giving partner's shoulders, while the pelvis tilts upward. That lift shortens the vaginal canal and steepens the angle, so penetration goes deeper than standard missionary with far less effort.

Try this: before you lift her legs, slide a firm sex wedge under her hips. It holds the tilt the whole position depends on, so her lower back can relax and you are not propping her up with your arms. Comparing shapes first? Our guide to the best sex position pillows lines up the wedges that actually keep that angle.

Picture missionary, then imagine her folding upward. Her thighs press toward her body, her hips rise to meet you, and you settle in close above her, forearms near her shoulders, chest almost against her legs. The name comes from the shape you make together. She is the anvil, braced and open. You are the weight coming down, slow and deliberate.

What makes it special is that it keeps everything missionary gives you. The face-to-face closeness, the eye contact, the ability to kiss her mid-stroke. It just trades the gentle depth of missionary for something that reaches all the way. If you have loved the intensity of the deep sofa positions but wanted more skin and more closeness, the anvil is where those two worlds meet.

To do the anvil, start in missionary, then have the receiving partner lift both legs up toward the chest while the giving partner rests those legs against their torso or shoulders and leans in close. The pelvis tilts up, the angle deepens, and you move slowly from there. It takes about ten seconds to set up and a little practice to find the perfect angle for your bodies.

Here is the flow we walk couples through, in five unhurried steps:

1. Start in missionary. Let her get comfortable on her back, a firm pillow or wedge under her hips. Kiss her. Do not rush the entrance.
2. Lift her legs. Guide both legs up toward her chest. She can hold behind her thighs, or you can take her ankles and rest her calves against your chest or shoulders.
3. Tilt the pelvis. As her legs rise, her hips roll upward. That tilt is the whole trick. It is what turns missionary into the anvil.
4. Lean in and anchor. Bring your weight forward onto your hands or forearms, near her shoulders, and find a depth that feels good for both of you before you add any pace.
5. Move slow, then build. Start with shallow, unhurried strokes or small grinding circles. Read her breath. Let her ask for more before you give it.

The receiving partner stays in control the entire time. If the angle feels too intense, she simply lowers her legs a few inches and the depth softens instantly. That adjustability is why the anvil is easier to enjoy than it looks.

In the anvil, the receiving partner sets the angle and the depth with her legs, while the giving partner supplies the rhythm and carries his weight on his hands or forearms. She is not passive here: pressing her calves against his chest is a built-in brake, and easing that pressure is how she asks for more.

• If you are on your back: breathe out as your legs come up, hold behind your thighs if your hamstrings are tight, and use your feet on his chest to steer. Your hands stay free for his hips, the headboard, or yourself.
• If you are on top: kneel close rather than hovering high, keep your weight off her legs, and hold her thighs or ankles lightly so she feels supported, not pinned. Watch her face more than your rhythm.
• Both of you: agree on two words before you start, one for deeper and one for ease off. Mid-stroke is not the time to negotiate.

Couples who enjoy that held, slightly surrendered feeling often find the anvil opens a door to gentle power play. If that sounds like you, our guide to remixing missionary has more ways to play with who leads.

The anvil feels deep because raising the legs and tilting the pelvis physically shortens the vaginal canal and lines the bodies up so the giving partner reaches the deepest point with almost no wasted motion. Nothing about your anatomy changes. The geometry does. That shorter path plus the steeper angle is what creates that full, pressing sensation couples chase.

That depth puts pressure on internal erogenous zones that a flatter angle glides right past. For a lot of women, that deep-pressure feeling is a different kind of pleasure than clitoral stimulation. It is fuller, heavier, more all-consuming. But here is the honest part most position guides skip. Deep penetration alone is usually not enough on its own. Only about 18 percent of women reliably orgasm from intercourse without added clitoral touch, so the anvil works best when you treat depth as one instrument in the song, not the whole band. In a nationally representative survey of 1,055 American women, 36.6 percent said clitoral stimulation was necessary for orgasm during intercourse (Herbenick et al., 2018).

That is where a little help earns its place. A slim clitoral vibrator pressed where the two of you meet turns the anvil from deeply satisfying into unforgettable. The deep pressure and the buzz stack, and most couples feel the difference on the very first try. If your hands are busy holding her legs, a vibrating couples ring worn at the base keeps that buzz exactly where you meet, hands free.

To make the anvil more comfortable, slide a firm cushion under the receiving partner's hips, warm up in an easier position first, and never force the legs higher than they want to go. Comfort is what lets you stay in the position long enough to actually build toward a finish instead of tapping out early.

The single biggest upgrade is support under the hips. A folded pillow works in a pinch, but it flattens fast and slips at the worst moment. A firm, wedge-style position pillow holds the pelvis at the ideal tilt, takes the strain off her lower back, and means you are not holding all her weight with your arms. Couples tell us it is the difference between a position they try once and one they come back to.

A quick comfort checklist before you go deep:

• Warm up first. The anvil is not a cold-open position. Build a sweat somewhere gentler before you fold her up.
• Prop the hips. Firm cushion under the pelvis, not a soft one that collapses.
• Mind her flexibility. Legs on the chest is enough. Legs on the shoulders is the advanced version. Only go there if it feels good.
• Start shallow. Depth is a dial, not a switch. Ease into it.
• Protect the sheets. A waterproof blanket under the wedge means nobody is thinking about the mattress, so you can stay a while.
• Keep talking. A whispered slower or right there is part of the fun, not an interruption.

The best anvil variations adjust leg height and angle to change how deep and how intense it feels: legs on the chest for a gentler version, legs on the shoulders for maximum depth, and a raised-hips version with a wedge for the steepest angle. Each one is the same core position with the intensity turned up or down.

Here is a quick map so you can pick the right one for the mood you are in:

Variation	Depth	Best for
Legs on the chest	Deep	First-timers, slow build, more control
Legs on the shoulders	Deepest	Flexible partners chasing maximum intensity
Wedge under hips	Deep + steep angle	Comfort, longer sessions, less back strain
Anvil + clit toy	Deep + full	Closing the orgasm gap, blended climax
Half anvil	Medium-deep	Tight hamstrings, cramps, easing in
Kneeling anvil	Deep	Watching each other, more leverage for him
Edge-of-bed anvil	Deepest	Taller partners, standing control

Three of these deserve a little more detail:

• Half anvil. Only one leg comes up onto his shoulder while the other stays bent on the bed or wraps around his waist. You keep most of the depth with half the stretch, and it is the easiest way back in if a calf cramps mid-session.
• Kneeling anvil. He kneels upright between her thighs and holds her ankles or calves against his chest instead of leaning over her. Less chest-to-chest contact, more of a view, and a little more control over pace for him.
• Edge-of-bed anvil. She lies with her hips at the edge of the mattress, legs up against his chest, while he stands on the floor. Great when he is much taller, since standing lines the hips up without any planking. Our guide to sex positions for height difference builds on the same trick.

If you and your partner love mixing depth with variety, the anvil slots beautifully into a longer session. Move into it from missionary, ride the intensity, then ease back out. Couples who like to keep things fresh often pair it with the ideas in our guide to creative sex positions worth trying, using the anvil as the deep, breathless peak in the middle. If you love that deep, folded-up angle, the frog sex position is its rear-entry cousin worth trying next. When you want the same depth from behind, the flatiron sex position turns the anvil's hip lift face down.

The anvil is missionary folded in half. She lies on her back, but instead of her legs wrapping his hips, they get lifted up over his shoulders so her knees hover near her chest. That single change tilts her pelvis up, shortens the canal, and turns a familiar face-to-face position into the deepest angle in the missionary family.

Couples often tell us the switch feels dramatic even though it starts from the most ordinary position in the book. One breath you are in classic missionary, the next her hips are stacked, his weight sinks forward, and every slow stroke lands somewhere new. If you love the eye contact of missionary but want more depth, the anvil is the natural next step, and the full nelson and piledriver wait one step past that when you are ready to go deeper still.

People often mix up the anvil with the seashell. In the seashell, her knees curl tightly toward her chest and fall out to the sides, a compact, contained fold. In the anvil, her legs rise straight up against his chest or shoulders, which opens the angle and lets him lean in closer. And if you like the anvil but want him standing, the butterfly sex position moves the same legs-up shape to the edge of the bed.

You do not need a dancer's hamstrings for the anvil. Start with her legs resting on his chest instead of over his shoulders, keep her knees slightly bent, and only raise them as far as her body opens up comfortably. Warmth and a little support do most of the work, so let the depth build over a few minutes rather than forcing the fold on the first try.

Slide a firm cushion under her hips and the whole position lifts into place on its own, no straining required. A dedicated wedge pillow holds the tilt steady so she can relax her lower back and simply feel every stroke instead of holding the pose. Breathe out as her legs come up, ease in slowly, and stop the moment anything pinches. If a fuller fold still feels like too much tonight, the gentler sofa lean gives you a similar depth with far less bend.

Research on sexual comfort backs the slow approach: relaxed pelvic muscles make deep positions feel better and safer, which is why easing in beats muscling through (per ACOG).

The mistakes that ruin the anvil are going deep before she is warmed up, letting his full weight press her knees into her chest, and skipping hip support so she has to hold the fold herself. Fix those three and the position goes from awkward to effortless.

• Starting at full depth. The tilt makes everything reach further than it does in missionary. Begin shallow and let her pull you deeper.
• Folding her too far. Knees near the chest is plenty. Pushing her legs past her comfort strains the hamstrings and the lower back.
• Dead weight on her legs. His weight belongs on his hands, forearms and knees. If she has to brace to breathe, he is leaning too hard.
• Pounding instead of grinding. Long, hard strokes in this angle can hit the cervix. Small circles and slow rocking feel deeper and kinder.
• No support under the hips. Without a cushion she does all the work of holding the tilt and tires in minutes.

The anvil is safe for most couples as long as you warm up, control the depth, and stop if anything feels sharp rather than intense. Because it allows very deep penetration, the main risks are discomfort from hitting the cervix too hard or straining the lower back, and both are easy to avoid with a slow pace and hip support.

Listen to the difference between deep and painful. Deep is a full, pressing pleasure. Pain is a sharp pinch or a dull ache, and it is your cue to lower her legs or slow down. Plenty of natural lubrication helps too, since depth without glide can feel like friction instead of bliss. If either of you has back or hip issues, the wedge version is your friend. For a broader primer on comfort and pleasure, resources from the American College of Obstetricians and Gynecologists are a trustworthy place to start.

Aftercare matters as much as setup. When the last wave fades, let her legs down slowly, pull her in, and stay close for a minute. The anvil is intense, and that closeness afterward is part of what makes couples want it again. If you want more ways to keep that connection alive between the big nights, our take on staying close without sex is a good next read.

No. You can do the anvil with the receiving partner's legs resting on the giving partner's chest and knees slightly bent, instead of straight up over the shoulders. A wedge or firm cushion under the hips creates the upward tilt for you, so the depth comes from angle and support rather than flexibility. Raise the legs only as far as feels comfortable and stop if anything pinches.

The full nelson and piledriver reach slightly deeper because they stack the body more steeply, but they are also more advanced and demanding. The anvil gives you most of that depth while staying face-to-face and far easier to hold, which is why many couples treat it as the sweet spot between everyday missionary and the truly advanced deep positions.

The anvil is a deep-penetration variation of missionary where the receiving partner lies on their back and lifts both legs up toward their chest or over the giving partner's shoulders, tilting the pelvis upward. This shortens the vaginal canal and opens the angle so every stroke lands deeper. It works best when both partners move slowly and stay connected.

The anvil should not hurt when you warm up first and control the depth. Because it allows very deep penetration, going too fast or too hard early can feel uncomfortable. Start shallow, add a cushion under the hips, and let the receiving partner set the pace. If anything pinches or aches, ease the legs down a little to reduce the angle.

Yes. The anvil is one of the deepest positions you can do lying down. Raising the legs and tilting the pelvis shortens the distance to the cervix and stacks the bodies so the giving partner can reach maximum depth with less effort than positions like doggy. That depth is exactly why couples chasing intense, full sensation love it.

In missionary the legs stay open and roughly flat. In the anvil the receiving partner pulls both legs up high, toward the chest or onto the giving partner's shoulders, which lifts the hips and steepens the angle. That single change turns a gentle, face-to-face position into a deep, high-intensity one while keeping the eye contact and closeness of missionary.

A firm pillow or cushion under the hips is not required, but it makes the anvil far more comfortable and easier to hold. It props the pelvis at the ideal angle, takes strain off the lower back, and lets the receiving partner relax into the position for longer without their partner having to hold all the weight.

In the anvil, the receiving partner lifts her legs straight up against her partner's chest or shoulders, which opens the angle so he can lean in close. In the seashell, her knees curl tightly toward her chest and fall out to the sides, a more compact fold. Both are deep, but the anvil is easier to hold for longer.

For the giving partner, the anvil feels tighter and deeper than missionary because her raised legs narrow the angle, and he gets a full view of her face. It also asks more of his arms, so resting on the forearms and using small grinding movements keeps it comfortable for both of you.

The anvil is not about acrobatics or proving anything. It is about that moment when you fold her up, lean in close, and everything gets quiet and deep and slow. Warm up, prop her hips, keep your eyes on hers, and let the depth build instead of forcing it. Do that, and this one position can change what an ordinary night feels like.

When you are ready to make it even better, the right cushion and a little buzz where it counts are all it takes. Those small, thoughtful upgrades are what we care about most. Go slow. Go deep. Stay close.

Where to go next:

• Want to sit up and take control? The captain sex position is the upright cousin of the anvil.
• Chasing the same depth with a head rush? The waterfall position drapes one partner over the edge of the bed.
• Ready to go further? The full nelson reclines the same fold into his arms, and the piledriver position takes the legs past the shoulders.
