with the girl on top I can literally last forever.. with me on top I can still control when I come but occasionally I just get too excited and don't slow down when I really should .
I really like to be in control so on top works for me. But, sometimes I don't care so on top or on the bottom works for me also.
I like either, but I love it when the women takes control. It shows me that they know how to handle themselves and I can't stand it when the women will never be on top.
Hehe, that reminds me of a story one of my friends once told me. His grandpa was talking to his uncle, and his uncle asked him "So, have you been getting any on the side?" and his grandpa (who he says is extremely cool) says "I haven't had any in so long, I didn't know they moved it!"
i prefer variation... a little from top, a little from bottom... a little from front and a little from behind.
