Woman on Top: In this position the girl can control the rhythm of the sex, and is more able to control how far the man is penetrating her. If she wants to be teased she can make shorter strokes, if she wants it deep she can thrust harder. Whatever the case, females rank this position as one of their favorites. Men love it too because they can lay back and enjoy the action.
Woman Sitting / Man Standing: This can be done in a variety of places, and sometimes a result of spontaneous sex. One of my favorites is placing the woman on the counter top, or on a desk. These typically provide the right height for both man and woman to enjoy it the most. This position can also be done with a chair, or anywhere that the woman can place her pelvis at the man's erect penis height.
Doggy-Style: Probably every woman's favorite because in this position the man can penetrate more deeply than ony other position. Plus I think most women enjoy the feeling of being dominated that this position provides. I like it a lot because I can reach around to play with her clitoris as I am pumping. This usually helps the woman orgasm more quickly and may help her have multiple orgasms.
