Prone Bone
A flat, face-down position for deep, grinding sensations.
About This Position
The receiving partner lies flat on their stomach while the penetrating partner lies on top and enters from behind. This position offers deep penetration with minimal effort and full body contact.
Best For
Clitoral Stimulation
Limited direct clitoral stimulation from the position itself, but accessible with a hand.
The receiving partner or penetrating partner can reach the clitoris with a free hand.
G-Spot Stimulation
Good G-spot stimulation from the angle of entry. The prone position creates a natural upward curve.
The angle targets the anterior wall; a pillow under the hips enhances this further.
Anatomy & Physiology

Body Contact Points
Step-by-Step Guide
The receiving partner lies flat on their stomach on a comfortable surface, legs together or slightly apart, with hips relaxed.
Tip: The prone position creates full-body contact along the back — the penetrating partner's chest rests against the receiving partner's back.
The penetrating partner lies on top, positioning their pelvis between the receiving partner's thighs. The slightly downward angle of penetration targets the posterior wall.
Tip: Place a pillow under the receiving partner's hips to elevate the pelvis and improve the angle.
Enter slowly from behind. The receiving partner should remain completely relaxed — the prone position requires zero effort from them.
Tip: This is rated Easy difficulty and has no joint stress, making it ideal for relaxation.
Use a grinding motion rather than thrusting — press your pelvis forward and rock side to side. The glutes and lower back drive the movement.
Tip: Grinding creates deeper internal stimulation along the posterior wall and G-spot area (rated 4/5).
The receiving partner can spread their legs slightly to adjust the angle of penetration and increase comfort.
Tip: Wider legs create more space for deeper penetration; keeping legs together creates tighter friction.
Use hands to caress the receiving partner's back, hips, or reach around to stimulate the clitoris (rated 2/5 without manual assistance).
Tip: Clitoral stimulation requires reaching around — the receiving partner can also use their own hand.
Rock gently together in a slow, rhythmic motion. The full-body contact and slow pace create an intimate, sensual experience.
Tip: This position is excellent for pregnancy (with modifications) due to the relaxed, low-effort nature.

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 Prone Bone position:
Putting too much weight on the receiving partner
The penetrating partner's full body weight on the receiving partner's back makes it hard to breathe and reduces comfort. Support your weight on your forearms or elbows.
Using thrusting instead of grinding
The prone position's advantage is the grinding, full-contact sensation. Piston-like thrusting misses the point and can be uncomfortable. Rock your pelvis in circular or forward-back motions.
Not using a pillow under the hips
Without hip elevation, the angle of penetration may not reach the G-spot effectively. A pillow under the receiving partner's hips tilts the pelvis for optimal internal stimulation.
Ignoring the receiving partner's breathing
Lying flat on the stomach with a partner on top can restrict breathing. Always check that the receiving partner can breathe comfortably and adjust your weight accordingly.
Variations to Try
Once you've mastered the basic Prone Bone, 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.
