Hummingbird: face to face on an exercise ball

The Hummingbird is a face-to-face position that uses an exercise ball. The receiving partner reclines on her back over the ball, back arched, with one leg raised over the penetrating partner's shoulder and the other wrapped around his waist. He kneels on the floor in front of her, torso upright and leaning towards her, holding her in his arms. Penetration is vaginal and usually deep. There is eye contact and room for kisses, but the ball rolls, so it calls for balance, some hip flexibility and a calm pace.

Anatomy and biomechanics

The receiving partner lies back over an exercise ball, her back arched over its curve and her buttocks resting on the front of the ball. One leg goes up, resting over the penetrating partner's shoulder; the other wraps around his waist, so her legs are wide apart and her pelvis is open towards him. The penetrating partner kneels on the floor facing her, torso upright and leaning forward, and puts his arms around her, which also steadies the ball. He controls rhythm and depth with his hips. Her back and buttocks rest on the ball and part of her weight on his arms; his knees take his weight on the floor. The raised leg and the arch ask for flexibility in the hips and lower back.

Why this position works

Many couples enjoy the mix of closeness and novelty: they are face to face, can look at each other and kiss, and his arms around her give a sense of security. The ball gives a little with each movement, which some people find adds a gentle rocking. With one leg raised, penetration is deep, and the arch of the back changes the angle in a way some women find pleasurable. Sensations vary from person to person.

Variations of this position

Variation 1: both legs around his waist

The receiving partner lowers the raised leg and wraps both legs around the penetrating partner's waist.

Without the leg on the shoulder, the hips need much less flexibility and her legs help hold the couple together, so the position is more stable. Penetration becomes a little less deep and the bodies come closer.

  1. Start in the Hummingbird, with him holding her firmly.
  2. She slowly lowers the leg from his shoulder.
  3. She wraps both legs around his waist and crosses her ankles behind him if comfortable.
  4. Continue with slow movements, keeping the ball steady.

Variation 2: ball wedged against the sofa or bed

The exercise ball is placed against the front of a sofa or the side of the bed, so it cannot roll backwards.

The furniture blocks the ball, which removes most of the instability. The posture is the same, but he can use his arms less for balance and more for caressing, and the pace can be a little firmer.

  1. Push the ball against the front of a sofa or the side of the bed.
  2. She reclines over it with her back arched, as in the basic position.
  3. He kneels in front and checks that the ball does not move.
  4. Raise one leg to his shoulder and start slowly.

Variation 3: her hand on the floor for support

The receiving partner reaches back or to the side and rests one hand on the floor beside the ball for extra support.

Her hand on the floor gives a third point of support and lets her control how much the ball rolls. He can then move his hands from her back to her hips to guide the rhythm.

  1. Start in the Hummingbird.
  2. She lets one arm drop and places the palm flat on the floor beside the ball.
  3. He moves his hands to her hips once she feels steady.
  4. Keep movements slow; she pushes on the floor if the ball starts to roll.

✓ Tips

  • Use a well-inflated exercise ball of a suitable size, on a non-slip surface such as a mat or rug, with nothing hard nearby.
  • The penetrating partner should hold her firmly: his arms keep both her and the ball steady.
  • Raise the leg only as far as feels comfortable; if the hip or hamstring pulls, keep both legs around his waist.
  • Start slowly and with shallow strokes: with one leg raised, penetration is deep.
  • Use lubricant if needed, and a cushion under his knees.
  • Avoid it with lower back or hip problems, or if balance is an issue.
  • Stop at once if the ball starts to roll or there is pain.

Frequently asked questions

What size of ball is best?

One that lets her hips sit roughly at the height of his pelvis when he kneels. For most people this is a 55 or 65 cm ball, but try it before you start.

Is it suitable for beginners?

It is better for couples who already feel confident: the ball rolls and the raised leg requires flexibility. Practise getting into position slowly first.

How can we stop the ball from moving?

Place it on a non-slip mat, push it against a sofa or the bed, and let him hold her firmly. Some couples wedge it with cushions.

What if the raised leg is uncomfortable?

Lower it and wrap both legs around his waist. Penetration will be a little less deep, but the position becomes more stable.
