Interesting points from Lorelei - unusally long cocks can reach in from awkward positions. But think of all the close contact positions you'd have to give up. Lie your man on his back on the floor. Squat over him and slide down his pole. If you can bounce up and down feeling comfortably full, good for you both. If you can't reach bottom without feeling you're about to be shish-kebabed and you have to move very carefully, oh well, that's life.

Personally I prefer to have a lady free to bounce up and down without a care.
