The Whispering Whirlpool: inverted position, him on top facing her feet

The Whispering Whirlpool is an inverted, advanced position. The receiving partner lies flat on her stomach with her legs straight and slightly apart, and the penetrating partner lies face down on top of her in the opposite direction, his head towards her feet and his pelvis over her buttocks. Penetration can be vaginal or anal and is of medium depth. It demands a lot of strength and control from the partner on top, and the reversed angle puts the penis at real risk, so it is for experienced couples who go very slowly.

Anatomy and biomechanics

The receiving partner lies flat on her stomach on the bed, legs straight and slightly apart, arms stretched forward. The penetrating partner lies face down on top of her but facing the other way: his pelvis rests over her buttocks, his torso lies along her legs and his head points towards her feet, while his feet end up near her shoulders. He grips her ankles to steady himself, and she can hold his feet by her head. Because he faces the opposite way, the penis enters bent against its natural curve, which is what makes the position demanding and risky. He controls the movement with small hip motions; she has very little room to move. Bodies are in contact along their whole length, but there is no eye contact and part of his weight rests on her.

Why this position works

Some couples are drawn to it for the novelty: the inverted angle produces sensations that are different from any usual rear-entry position, and the full-length body contact can feel very enveloping. The partner underneath can simply let go while the partner on top leads. The appeal is mostly in trying something unusual, carefully; it is not a position for long or vigorous sex, and sensations vary from one person to another.

Variations of this position

Variation 1: him kneeling astride

He kneels astride her legs instead of lying flat on them.

Instead of lying along her legs, the penetrating partner kneels with one knee on each side of her thighs, still facing her feet, and leans forward on his hands beside her calves. Much less of his weight rests on her, and he has more control over the angle and depth, which makes the position safer for the penis.

  1. She lies face down with her legs straight and slightly apart.
  2. He kneels astride her thighs, facing her feet, with his hands on the bed beside her calves.
  3. He lowers his pelvis onto her buttocks and guides the penis in by hand, very slowly.
  4. He moves with small hip motions, keeping his weight on his knees and hands.

Variation 2: legs together

She keeps her legs together and he places his knees outside them.

The receiving partner closes her legs completely and the penetrating partner places his knees or legs outside hers. The entrance becomes narrower, which some couples find gives a snugger feel, and penetration is a little shallower.

  1. She lies face down and brings her legs together.
  2. He gets into position on top, facing her feet, with his legs outside hers.
  3. He enters slowly; the closed legs limit depth.
  4. Keep the movement small and stop if the angle feels forced.

Variation 3: pillow under her hips

A firm pillow under her pelvis raises her hips and eases the angle.

The receiving partner places a firm pillow or wedge under her pelvis. Her hips rise, so the penis has to bend less to enter and the pressure on her abdomen is reduced. The rest of the position stays the same.

  1. Place a firm pillow or cushion under her pelvis before getting into position.
  2. She lies face down over the pillow, legs straight and slightly apart.
  3. He gets into position on top, facing her feet, and checks that the angle feels comfortable for the penis.
  4. Adjust the height of the pillow until neither of you feels strain.

✓ Tips

  • Go very slowly: the penis enters bent against its natural curve, and a sudden thrust or a slip can cause a penile fracture. If it slips out, stop and guide it back by hand.
  • The partner on top should keep most of his weight on his knees, arms and her legs, not on her lower back or abdomen; she must be able to breathe comfortably.
  • Use a firm mattress and build up the position step by step; if anyone feels unstable or loses control, stop.
  • For anal sex, use plenty of lubricant and a condom, and never switch from anal to vaginal without changing the condom.
  • Stop immediately if there is any pain; a crack, sudden pain or loss of erection in the penis needs urgent medical attention.

Frequently asked questions

Is this position for beginners?

No. It requires strength, balance and good communication, and the reversed angle puts strain on the penis. It is best tried only by couples with experience, slowly and briefly.

Why is it risky for the penis?

Because the partner on top faces the opposite direction, the erect penis is bent backwards to enter. Strong thrusts or a slip can injure it. Keep movements small and controlled.

Does it stimulate the G-spot?

It cannot be promised. The reversed angle changes where the pressure falls, and how it feels varies a lot from person to person.

Can it be done with anal sex?

Yes, with plenty of lubricant, a condom and a slow start. The same care with the angle applies.

Safety and evidence 5 topics · 10 clinical and academic references

This section summarizes anatomical and clinical evidence relevant to this position. The sources provide context; they do not show that a specific position guarantees pleasure, orgasm or a particular type of stimulation.

Anatomical variability

Vaginal shape, axis and dimensions vary considerably from person to person. As a result, depth and comfort may differ even when using the same position.

Lubrication and comfort

When there is dryness, friction or discomfort, a suitable lubricant may make sexual activity easier and improve comfort. Its use is not universally necessary.

Anal sex: care and prevention

The anus does not lubricate itself and its lining is thin. Plenty of lubricant, a condom, going slowly and being able to stop at any moment make it more comfortable and lower the risk of injury and infection.

Penile fracture: prevention and warning signs

It is uncommon, but it can happen when the erect penis bends suddenly, often after slipping out and hitting the partner’s pubic bone or perineum. Moving with control and slowing down if the penis slips out helps prevent it.

STI protection: condoms and dental dams

A condom, put on from the start and used throughout, is the most effective way to reduce sexually transmitted infections during penetration. For oral sex, a condom or a dental dam lowers the risk.
