The Anvil position is a face-to-face sexual position built around a deep fold: the receiving partner lies on their back and draws their legs up and back toward their own head, holding them there or resting them against the penetrating partner's shoulders, while the penetrating partner leans over from above to set the angle and pace. Whether you think of it as a position or a sex pose, the fold is what makes it distinct, and it is an intense, athletic option that rewards a slow start and good communication. It tends to suit couples who are already comfortable with deep penetration and want to try something that asks a bit more of the body. Because of how it folds the receiving partner's body, it is not the right fit for everyone, and knowing that going in makes it both safer and more enjoyable.
How to Do the Anvil Position: Step by Step
Warm up and stretch first. Since the Anvil position folds the body more than most, some light stretching for the hips, hamstrings, and lower back helps before you start.
Get into position. The receiving partner lies on their back and slowly draws their knees up toward their chest, then further back toward their head, holding the backs of their thighs to keep the fold steady.
Move in close. The penetrating partner kneels in front and leans forward over the receiving partner, supporting their own weight on their arms or knees rather than dropping their full weight onto the receiving partner's body.
Line up and enter slowly. The fold changes the angle and depth compared to most other positions, so ease in gradually and pause to check in.
Find a slow rhythm. This is not a position built for speed. Small, controlled movements tend to feel better than fast ones for both partners.
Adjust as you go. Changing how far the legs are folded back, or tucking a pillow under the receiving partner's hips, can shift both the comfort and the sensation.
4 Anvil Sex Position Variations to Try
Shoulder-rest Anvil. The receiving partner's legs rest across the penetrating partner's shoulders instead of being held by hand. This frees up the receiving partner's arms and can deepen the angle.
Ankle-hold Anvil. The receiving partner holds their own ankles or calves, which puts them in control of exactly how far the fold goes and makes it easy to ease off the moment anything feels tight.
Pillow-lifted Anvil. A firm pillow under the receiving partner's hips raises the angle without folding the legs as far back, which is gentler on the neck and lower back.
Side-lean Anvil. The penetrating partner leans to one side, supported on one arm, which takes some weight off the receiving partner's chest and allows for shallower, slower movement.
Who the Anvil Position Suits and Who Should Be Careful
The Anvil tends to suit people who already enjoy deep penetration and want an intense, athletic position with plenty of eye contact and closeness. Because it takes some flexibility and trust to settle into the fold comfortably, it works best for couples who have tried a few other positions together already and have a sense of what depth and pace they both like.
A few situations call for real caution. Anyone with neck, cervical spine, or upper back issues should avoid the Anvil altogether, since folding the legs back toward the head can put real strain on the neck and upper spine. It can also be hard on the receiving partner's hips and lower back if the fold goes too far, and hard on the penetrating partner's knees if they are kneeling for a while. If you are pregnant, check with your doctor before trying a folded position like this one, since comfort and safety needs change as pregnancy progresses. If anything pinches, aches, or just feels off for either partner, that is your cue to ease back or stop, not push through it.
Anvil Sex Position Comfort and Safety Tips
A water-based lubricant is a solid general choice for the Anvil sex position, since the deeper angle can create more friction than usual. If you are using latex condoms or dental dams, skip oil-based lubricant, since it can damage latex. If you are using silicone toys, skip silicone lubricant too, since it can break down the material.
Skip this position if the receiving partner has neck or spine problems. With hip, lower back, or knee problems, choose a gentler variation such as the pillow-lifted Anvil, or skip it if anything about the fold feels wrong once you are in it. Stop at any pain, for either partner, rather than trying to work through it.
The Anvil itself does not lower the risk of pregnancy or sexually transmitted infections, so barrier protection such as condoms still matters exactly as it would in any other position. If you are switching between anal and vaginal contact, use a fresh condom or barrier and wash up in between, since moving from anal to vaginal contact is what raises infection risk, not the position itself.
Talking About the Anvil Position and Consent
A quick conversation before and during sex makes the Anvil, or any position, better and safer for everyone involved. A few phrases that work well:
"Want to try the Anvil?"
"Is this angle comfortable, or should we ease back a little?"
"My neck feels fine, keep going."
"That's too much, let's stop."
Because this position folds the receiving partner's body more than most, it helps to check in more than once, since something that feels fine at first can start to pull on the neck or back partway through. Agree on a simple word or signal beforehand, something either partner can say or do without breaking the mood, so anyone can pause things at any point.
Anvil Position FAQ
Is the Anvil position hard on your neck?
It can be, since folding the legs back toward the head can put real strain on the neck and upper spine. Anyone with existing neck or spine issues should avoid this position, and everyone else should ease into the fold slowly and stop if anything pulls or aches.
Do you need to be flexible for the Anvil?
Some flexibility in the hips and hamstrings helps, since the receiving partner folds their legs back for a while. The pillow-lifted or ankle-hold variation makes the position more accessible if you are still working on flexibility.
Is the Anvil safe during pregnancy?
It depends on the stage of pregnancy and what feels comfortable. The deep fold this position asks for is not a good fit for many pregnancies, so check with your doctor and consider a gentler position instead as things progress.
Do you need a pillow for the Anvil?
You do not need one, but a lot of people find it more comfortable with a firm pillow under the hips. It helps with the angle and takes some of the fold, and the strain, off the neck and lower back.
Is the Anvil position a good fit for beginners?
It is better suited to couples who already have some experience together and a sense of what depth and pace they enjoy, since the fold and the deeper angle take some getting used to. Starting slow and communicating throughout makes it easier to learn.
