The Arching Encounter: seated face to face on the edge of the bed

The Arching Encounter is a seated, face-to-face position on the edge of the bed. He sits upright with his feet flat on the floor and holds her by the waist. She sits astride his lap, wraps her bent legs around his waist and rests her feet on the bed behind him, then arches her back and lets her head fall back, placing her hands on his knees. She sets the pace with small movements of her hips. It requires little effort, keeps the bodies close together and lets him kiss her chest; when she sits up again, they can look at each other and kiss.

Anatomy and biomechanics

He sits on the edge of the bed with his back upright, knees bent and feet flat on the floor, so he has a stable base. She sits astride his thighs facing him, her legs bent and wrapped around his waist, with her feet resting on the mattress behind him. From there she arches her back and tilts her head backwards, leaning her weight on her hands, which rest on his knees behind her. He holds her firmly by the waist so that she can arch without losing her balance, and his face is level with her chest. She controls the rhythm with her hips, and penetration is of medium depth. There is no eye contact while she is arched, but contact between pelvis and abdomen is broad. The load falls on her lower back, which is extended, and on his thighs, which carry her weight.

Why this position works

Many couples enjoy the mix of closeness and freedom: the bodies are pressed together, but by arching back she opens up her chest and sets her own pace. He has a direct view of her and can kiss her chest, and both can switch between the arch and an upright, face-to-face embrace with kisses. Some people find that the arched angle changes the sensation of penetration in a pleasant way, and either partner can reach the clitoris by hand. How it feels varies from person to person.

Variations of this position

Variation 1: sitting upright, chest to chest

She stays upright instead of arching back, with her arms around his neck.

Without the arch her lower back rests and the two torsos are pressed together. There is eye contact and kissing, and the movement becomes smaller and slower, more of a rocking. It is a good way to start, or to rest between moments of arching.

  1. He sits on the edge of the bed with his feet flat on the floor.
  2. She sits astride his lap facing him and wraps her legs around his waist.
  3. She keeps her back upright and puts her arms around his neck.
  4. She sets a slow rocking rhythm with her hips while you kiss.

Variation 2: he supports her back with his arm

Instead of holding her waist, he places one forearm across her upper back so she can arch with her hands free.

With his forearm under her shoulder blades, she no longer needs to lean on his knees and her hands are free to caress him or stimulate her clitoris. Her lower back is less loaded because his arm takes part of the weight. He needs a firm grip and an upright back.

  1. Get into the basic position, seated on the edge of the bed.
  2. He slides one forearm behind her upper back, at the level of her shoulder blades.
  3. She arches back gently, letting his arm take her weight, and frees her hands.
  4. He keeps the other hand on her waist while she moves her hips.

Variation 3: on a sturdy chair instead of the bed

He sits on a sturdy armless chair instead of the edge of the bed, and she straddles him in the same way.

A chair has a firmer, flatter seat than a mattress, so his base is more stable. Without the bed behind him, her feet cannot rest on the mattress: she crosses her ankles behind his back or rests her toes on the rungs or the floor. The arch and her hands on his knees stay the same.

  1. Choose a sturdy chair without armrests and place it against a wall or on a rug.
  2. He sits with his back upright and both feet flat on the floor.
  3. She straddles him facing him and crosses her ankles behind his back, or rests her toes on the floor.
  4. She arches back gently, hands on his knees, while he holds her waist.

✓ Tips

  • He should sit on a firm edge of the bed, with both feet flat on the floor and his back upright, so that he can hold her steadily.
  • She should arch only as far as her lower back allows and lean on his knees; he should keep a firm hold on her waist the whole time.
  • Avoid leaning back suddenly or with a lot of force: the angle of the penis changes and it could bend. Make the movements smooth.
  • Use lubricant if needed, and if her back or his thighs start to tire, sit up and rest in an embrace.
  • Stop if there is pain.

Frequently asked questions

Is it suitable for beginners?

Yes. Both partners are sitting and supported, so the effort is low. The only thing that takes practice is the arch: start with a slight lean and go further only if it feels comfortable.

Can it be done without arching back?

Yes. She can sit upright, chest to chest, with her arms around his neck. That way there is eye contact and kissing, and the lower back rests; it is the first variation below.

Is there any risk for the lower back?

Arching extends the lower back. If she has back pain, it is better to arch less or sit upright, and to stop if it hurts.

Can the clitoris be stimulated?

Yes. While she is arched, the clitoris is accessible: he can reach it with one hand while holding her with the other, or she can use one hand if he supports her back.

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.
