Anvil
A heavy, pounding position for maximum intensity.
About This Position
The receiving partner lies on their back with legs pushed back toward their head while the penetrating partner uses their body weight for powerful, anvil-like thrusts. This position is about raw power and intensity.
Best For
Clitoral Stimulation
Minimal clitoral stimulation from the extreme position.
Very difficult to access the clitoris in this position.
G-Spot Stimulation
Moderate G-spot stimulation — the extreme angle targets deeper areas more than the G-spot.
The angle bypasses the G-spot in favor of deeper pressure.
Anatomy & Physiology

- Hip flexors

Body Contact Points
Step-by-Step Guide
The receiving partner lies on their back and brings their legs back toward their head. The hamstrings, hip flexors, and lower back are under extreme stretch.
Tip: The receiving partner can use their thighs to control depth by pressing their legs against the penetrating partner's body.
The penetrating partner kneels above, using body weight for powerful, anvil-like thrusts. The extreme upward angle allows very deep penetration with significant force.
Tip: The deep spot, cervix, and anterior fornix are all targeted — this is rated 1/5 for clitoral stimulation.
Slowly enter from above, going very carefully at first. The extreme angle means even minimal entry is very deep. The penetrating partner's body weight adds force.
Tip: Control the intensity — the weight and angle combine to create powerful internal pressure.
The penetrating partner uses their body weight for anvil-like pounding — this is about raw power and intensity. The core and glutes generate the force.
Tip: The receiving partner's thighs can push back against the penetrating partner's body to control depth.
Control the intensity carefully. This position can be extremely powerful — what feels good can quickly become too much. Communicate constantly.
Tip: The extreme angle combined with body weight creates force that can bruise the cervix if uncontrolled.
Use the receiving partner's thighs to control depth if needed. The receiving partner pressing their legs against the penetrating partner's torso limits how deep they can go.
Tip: This is a Hard difficulty position — the extreme angle and intensity require experience and communication.
Communicate constantly about intensity levels. The anvil position is designed for maximum power — but maximum power without communication can cause pain.
Tip: Exit slowly — the hamstrings need time to release from the extreme flexion.

Common Mistakes to Avoid
Even with the right technique, small errors can reduce pleasure or increase injury risk. Here are the most common mistakes couples make with the Anvil position:
Using full force without warming up
The anvil position is about power, but starting with full-force pounding can cause cervical injury. Start gentle, assess comfort, then increase intensity gradually.
Not letting the receiving partner control depth
The penetrating partner has all the power in this position. Without using the receiving partner's thighs as a depth control, the penetration can become painful or dangerous.
Ignoring cervical contact
The extreme angle targets the cervix directly. Some people find cervical stimulation pleasurable; others find it painful. Communicate about this before using full force.
Holding the extreme leg position too long
The extreme hip flexion is demanding on the hamstrings and lower back. Holding it for extended periods causes cramping or strain. Keep sessions brief.
Variations to Try
Once you've mastered the basic Anvil, these variations can add new sensations and keep things exciting:
Add a Pillow
Place a pillow under the receiving partner's hips to change the angle of penetration and enhance stimulation.
Incorporate Manual Stimulation
Use hands to add clitoral or other external stimulation during the position for enhanced pleasure.
Slow Down the Pace
Switch from thrusting to grinding for a more intimate, sensation-focused experience.
Try Different Surfaces
Move from the bed to a couch, standing, or against a wall for different angles and experiences.
