How To Do It: Start off in missionary position. Have your partner sit back on their heels while you lift your legs up and place your heels on their shoulders. You can cross your legs, if that feels right, placing your left heel on their right shoulder and right heels on their left shoulder.
They should then lean forward, resting their weight on their hands. Your legs will get pushed back towards your head, and from there your partner can enter you with their penis or strap-on.
If that feels like too much of a strain on your legs, you can take them off their shoulders and hold them up in the air.
