The Rocking of the Waves: reverse cowgirl with the receiving partner in control

The Rocking of the Waves is a reverse-cowgirl-style position. The penetrating partner lies on their back with the legs stretched out and the upper body slightly raised on one forearm. The receiving partner sits astride their pelvis facing their feet, with the torso upright, knees bent and both feet flat on the bed on either side of their legs. The receiving partner sets the pace by rocking or rising and lowering with the legs, while the partner underneath can rest a hand on their back. Penetration can be vaginal or anal and is of moderate depth. There is no eye contact.

Anatomy and biomechanics

The penetrating partner lies on their back with the legs straight and props the upper body up a little on one forearm; the free hand rests on the receiving partner's back or side. The receiving partner sits on their pelvis facing their feet, torso upright and head slightly tilted back, knees bent and raised, feet flat on the bed on either side of the partner's legs. The receiving partner's weight is shared between the feet and the buttocks. Movement comes from the receiving partner: rocking the pelvis back and forth or rising and lowering by pushing with the legs, which works the thighs and knees. Because the penis is angled towards the partner's feet, a wide or abrupt movement can bend it; keep the movement controlled and do not lift off completely.

Why this position works

The receiving partner has full control of rhythm, depth and angle, which many people value, especially when exploring or after a pause. The partner underneath can relax and enjoy the view of their partner's back, and has a hand free to caress the back or hips. The receiving partner's hands are also free, so they can add manual stimulation if they wish. Sensations vary from person to person; changing the lean of the torso changes the angle.

Variations of this position

Variation 1: leaning forward

The receiving partner leans the torso forward and rests the hands on the lower partner's thighs or shins.

Leaning forward changes the angle of penetration and moves some of the weight onto the hands, which rests the thighs. The partner underneath gets a closer view of the receiving partner's back and buttocks. Keep the movement short: the angle makes the penis bend more easily.

  1. Start in the basic position, sitting upright.
  2. Lean the torso forward slowly and place the hands on the partner's thighs or shins.
  3. Keep the feet flat on the bed.
  4. Move with short, controlled rocking rather than wide strokes.

Variation 2: leaning back on the hands

The receiving partner leans back and supports themselves with the hands on the bed beside the lower partner's chest.

Leaning back brings the torsos closer and frees the front of the receiving partner's body, so the partner underneath can reach the chest or genitals with a hand. Movement becomes a gentle rocking; depth is reduced.

  1. From the basic position, the receiving partner leans back slowly.
  2. They place the hands on the bed on either side of the partner's chest.
  3. The partner underneath can put an arm around their waist for support.
  4. Rock the pelvis gently, without rising and dropping.

Variation 3: kneeling instead of feet on the bed

The receiving partner rests the knees on the bed on either side of the lower partner's hips instead of the feet.

Kneeling lowers the effort for the thighs and makes the position more stable; movement becomes a back-and-forth rocking rather than rising and lowering. It is a good option for longer sessions or when the knees bent with feet down get tired.

  1. From the basic position, the receiving partner lowers one knee and then the other onto the bed beside the partner's hips.
  2. They keep the torso upright or slightly forward.
  3. Move by rocking the pelvis back and forth.
  4. Place a soft surface under the knees if needed.

Variation 4: partner sitting up against the headboard

The penetrating partner sits up against the headboard or a pile of pillows, with the receiving partner still facing their feet.

Sitting up brings the chest of the penetrating partner against the receiving partner's back, so both arms are free to hug the waist, caress or kiss the neck. The receiving partner still leads the rhythm, with smaller movements.

  1. The penetrating partner sits with the back against the headboard or firm pillows, legs stretched out.
  2. The receiving partner sits on their pelvis facing their feet, feet on the bed.
  3. The partner behind wraps the arms around the waist or hips.
  4. The receiving partner moves with short rocking movements.

Variation 5: grinding without rising

The receiving partner stays fully seated and moves only by rocking or circling the pelvis, without rising and lowering.

Staying seated keeps penetration constant and the movement small, which is gentler on the thighs and lowers the risk of the penis bending. The pressure of the pelvis can be very pleasant for some people.

  1. Sit fully on the partner's pelvis with the feet flat on the bed.
  2. Rock the pelvis slowly back and forth.
  3. Try small circles or figure-of-eight movements.
  4. Keep contact at all times, without lifting off.

Variation 6: with a strap-on

The partner lying underneath wears a harness with a dildo; the receiving partner sits on top facing their feet as in the basic position.

The mechanics are the same, but the toy does not bend, so the receiving partner can move more freely; it is still worth going slowly. The harness should be well adjusted so it does not shift.

  1. Adjust the harness firmly and put a condom on the dildo if it will be shared.
  2. The partner wearing it lies on their back with the legs stretched out.
  3. The receiving partner sits on top facing their feet, with plenty of lubricant.
  4. Clean the toy after use.

✓ Tips

  • The receiving partner should go down slowly and keep movements controlled: with the penis angled towards the feet, a wide or abrupt movement can bend it painfully.
  • Mistake: lifting off completely and dropping back down; it is the most common cause of penile injury in positions with the receiving partner on top.
  • Use plenty of lubricant and a condom for anal sex, go slowly and stop if there is pain.
  • Use a condom to protect against STIs and, in vaginal sex, against pregnancy.
  • If the thighs or knees get tired, rest the knees on the bed or switch to rocking instead of rising and lowering.
  • The partner underneath can support the receiving partner's back or hips with one hand to give stability.

Frequently asked questions

Who controls the rhythm in this position?

The receiving partner, who is on top and moves by rocking or rising and lowering with the legs. The partner underneath mostly accompanies the movement.

Is it risky for the penis?

It can be if the movement is wide or uncontrolled, because the penis is angled towards the partner's feet. Moving slowly, not lifting off completely and stopping if there is pain reduces the risk.

Can it be used for anal sex?

Yes. The receiving partner controls depth and speed, which helps; use plenty of lubricant and a condom, and start very slowly.

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.

G-spot: what the evidence says

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

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.

Sex toys and strap-ons: hygiene and safe use

Washing toys after each use, putting a new condom on them when they are shared or moved between areas (for example, from the anus to the vagina) and using a lubricant that suits their material make them safer to use.

Clitoral stimulation and orgasm

For many women, the most reliable route to orgasm is clitoral stimulation, direct or indirect. A position that leaves hands free or lets the clitoris be rubbed makes it easier to add during penetration.

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.
