The Insinuator: kneeling rear entry with her over an exercise ball
The Insinuator is a doggy-style variation with an exercise ball. She kneels on the floor with knees apart and lets herself fall forward onto the ball, which supports her chest and abdomen; one hand stays on the floor for balance. He kneels behind her with an upright torso and sets the pace. The ball takes the weight off her arms and slightly changes the angle of her pelvis. Penetration can be vaginal or anal and is usually deep.
Also known as: Inseminator
Anatomy and biomechanics
The receiving partner kneels with legs apart and bent; the torso folds forward and the chest and abdomen rest on the ball, which carries almost all her weight. She keeps one hand on the floor on the far side of the ball so it does not roll, and lets her head relax. The penetrating partner kneels directly behind with a vertical torso, knees and insteps on the floor and hands on her lower back or hips. He controls pace and depth; she can rock a little on the ball. Body contact is minimal (pelvis and hands) and there is no eye contact or kissing. Both partners' knees bear load and there is some pressure on her abdomen.
Why this position works
The ball lets the receiver relax her arms and back and be supported, which is harder in classic doggy style. Gentle rocking on the ball adds a different movement. For the penetrating partner, the kneeling height lines up well. Sensations vary: some enjoy the depth and others prefer to keep it gentle.
Variations of this position
Variation 1: cushions instead of the ball
A stack of firm cushions replaces the ball: no rocking, but more stable.
The support does not roll, so she can let go with both hands and relax completely. The height of the cushions sets the pelvic angle: the higher they are, the more horizontal her back.
- Stack firm cushions to the height of her hips when she kneels.
- She kneels and rests her chest and abdomen on top.
- He kneels upright behind her.
- Adjust the cushion height until you are both comfortable.
Variation 2: she sets the pace by rocking
He stays still and she rocks back and forth on the ball.
Control of the pace is reversed: he keeps his pelvis still and she gently rolls the ball back and forth with her knees. She decides depth and speed.
- Start from the basic position.
- He stays kneeling and still, hands on her hips.
- She pushes gently with her knees to roll the ball back and forth.
- Go slowly until you control the movement.
Variation 3: the ball on the bed
With the ball or a large pillow at the edge of the bed, he can stay standing.
She kneels at the edge of the bed and drapes her chest over the ball or a large pillow; he stands on the floor at just the right height without loading his knees.
- She kneels at the edge of the bed.
- She drapes her chest over the ball or a large pillow.
- He stands on the floor behind her.
- Adjust the height with his legs.
✓ Tips
- Use a well-inflated exercise ball of the right size; she should keep one hand on the floor so it does not roll.
- Put a rug or cushions under both partners' knees.
- If the ball's pressure on her abdomen is uncomfortable, she can rest more on her chest or let some air out.
- Penetration can be deep: start slowly and let her say when to slow down.
- Avoid hard thrusts if the penis slips out: a blow to the erect penis can injure it.
- For anal penetration, plenty of lubricant and a condom; never move from anus to vagina without changing it.

Who controls the pace?
He does, kneeling behind; she can join in by rocking on the ball.
Safety and evidence
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.
Pain and deep penetration
If penetration causes deep, recurrent or persistent pain, it is advisable to reduce the depth or stop the activity. If the problem continues, a professional assessment is recommended.
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.
