I'm a girl and idk if you really want my answer or not, but I had this close friend (we would probably be dating now, except I moved away from Reno and shortly after he moved to Washington State - we lived in the same apartments) and he had a big cock - about 10 inches I guess. Anyway, I'm not really a big fan of being on top, but I tried it once with him and omg it hurt so damn bad... I think what made it hurt the worst was leaning back... I didn't mean to really, but when I did... omg I thought it was going to kill me... needless to say I didn't stay on top for very long.
