The Fertile Heat: rear entry with him on his shoulders

The Fertile Heat is an unusual, acrobatic variation of rear entry. The receiving partner gets on all fours, on her hands and knees. The penetrating partner lies behind her on his shoulders and upper back, with his hips raised and his legs folded over his body, resting his feet on her lower back. She does the moving, pushing her hips back towards him, and penetration can be deep. It demands a lot of both partners, especially from his neck, and it is held only for a short time.

Anatomy and biomechanics

The receiving partner kneels on all fours, hands flat on the bed and knees apart, facing away from her partner. The penetrating partner lies behind her, rolled back onto his shoulders and upper back, with his pelvis raised to the height of hers and his legs bent and folded over his torso. He rests his feet on her lower back, which helps him keep his balance and lets him accompany her movement. His weight must rest on his shoulders and upper back, never on his neck. She sets the rhythm by moving her hips backwards and forwards towards his raised pelvis, and controls depth, which can be considerable. Her wrists and knees carry the load; his neck and upper back are the most exposed area.

Why this position works

Some couples try it for its novelty and the playful challenge it represents. The receiving partner fully controls the rhythm and depth while her partner stays in an inverted position, which changes the usual roles of rear entry. The angle is very different from a classic doggy style, and some people find it intense, although this varies from one body to another. It is a position for experimenting for a short while, not for a long session.

Variations of this position

Variation 1: She Rests on Her Forearms

The same position, with the receiving partner lowering herself from her hands onto her forearms.

He stays on his shoulders with his hips raised and his feet on her back. She lowers her chest and rests on her forearms, which lowers her pelvis slightly and changes the angle of entry. Her wrists rest, and her movements become shorter and more controlled. It is also a way to adjust the height if his pelvis ends up lower than hers.

  1. Get into the basic position.
  2. She bends her elbows and rests her forearms on the bed, with a cushion under them if she wants.
  3. He adjusts the height of his hips and keeps his feet on her lower back.
  4. She moves her hips backwards and forwards with short movements.

Variation 2: Cushion Under His Lower Back

A firm cushion or folded pillow under his lower back helps him hold his hips up without effort.

The mechanics are the same, but his raised pelvis rests partly on a firm cushion instead of depending only on the strength of his back and abdomen. His neck and upper back carry less load and he can hold the position longer and more steadily. The cushion height also adjusts the height of his pelvis to hers.

  1. Place a firm cushion or folded pillow where his lower back will be.
  2. He lies on his back, lifts his hips and rests his lower back on the cushion, with his legs folded over him.
  3. She gets on all fours with her back to him and brings her pelvis to his.
  4. He rests his feet on her lower back and she starts moving slowly.

Variation 3: Slow Rocking

Instead of pushing back in long strokes, she keeps him inside and rocks her hips in small circles or short movements.

The posture does not change; only the rhythm does. By keeping the penis inside and moving in small circles or very short strokes, there is far less risk of it slipping out and bending, and his neck has to absorb less movement. The sensation becomes more continuous and less intense, which is useful for getting used to the position.

  1. Get into the basic position.
  2. She pushes back until he is inside and stays there.
  3. She rocks her hips in small circles or with very short back-and-forth movements.
  4. He keeps his feet on her lower back to accompany the movement.

✓ Tips
  • Do it on a firm, non-slip surface, with a cushion or folded blanket under his shoulders; his weight should rest on the shoulders and upper back, never on the neck.
  • He can support his lower back with his hands to stay stable; stop as soon as either of you feels unsteady or he notices pressure or pain in the neck.
  • She should move slowly and with short strokes: if the penis slips out and she pushes back onto it at an angle, it can bend and be injured.
  • Put something soft under her knees and hands, and take breaks if her wrists get tired.
  • Use lubricant if needed and stop if there is pain.

Frequently asked questions

Is it suitable for beginners?

No. It requires flexibility and strength from the penetrating partner, who has to hold an inverted position, and coordination from both. Try it only if you are already comfortable with simpler rear-entry positions.

Who controls the movement?

The receiving partner. She sets the rhythm and depth by moving her hips backwards and forwards; he mainly keeps his position and accompanies her with his feet.

Is it risky for the neck?

It can be if the weight falls on the neck. Keep it on the shoulders, use a cushion underneath and stop if there is any discomfort. If he has neck or back problems, it is better to choose another position.

Can we make it easier?

Yes: a firm cushion under his lower back helps hold the hips up, and she can lower herself onto her forearms to adjust the height.

G-spot: what the evidence says

“G-spot” is a widely used term for a sensitive area of the anterior vaginal wall. Scientific literature has not established a discrete anatomical structure with an agreed location, size and nature; sensitivity and response can vary between individuals.
