lgmember9: I have been told that the best position is either "Doggie Style" or "Woman on Top Facing Away" by my wife. She says that my penis really fills her up that way, and she is able to achieve a vaginal orgasm more frequently. My penis is 9.5"x6.5" so I guess a larger one might alter the answer somewhat. What do the ladied on the site think? Also, does penis size effect the position you like best? My wife and I would both like to know.
