10. the Swing

The man lies on his back. The woman turns her back on him and crouches down on his lingam, supporting herself on her feet. Or she kneels down with her legs on either side of her partner's hips, for a greater amplitude of motion.

Plusses
This position offers the man an exceptional view of his partner's behind, and of the penetration.
It allows a good amplitude of motion, particularly with the woman kneeling down, to procure maximum pleasure to the man and lead him rapidly to orgasm.

Minuses
The angle of penetration can make the position uncomfortable for some men.
