My favorites change with the mood and with the woman. Missionary-- in its variations -- is the most intimate. Female anatomy changes which works best for her. Cowgirl can be the hottest because she can control her entire ride, orgasm after orgasm. Doggy tends to hit the g-spot best. I like the various scissor positions, her on her side for really deep penetration. Standing with her on the bed or chair is good for hard and long time pounding, if that is her taste... and on and on.
