Interestingly enough I have incredible sexual stamina. Not only can I go as long as the woman wants, but I bounce back pretty fast. They always tapout before I do.
Don't know if this counts but I have learned to Never Say Never [James Bond taught us that] If she wants it I just go along with her.
One thing I've always done is to let my partner know how beautiful they are and how much I enjoy being with them. I've fucked some knockouts and some not so's plus many in between. Of the 30 plus different women I've had carnal knowledge of all except one has been a blast in bed. (The one was very attractive but it just didn't work) Super power? Being nice and talking. Not about me but showing interest in her and her life. Once you get her mind opened up sex is fantastic.
