So here's the story. I've been with my gf for over a year, and had been "hooking up" for a year before we started dating. Thing is, i'm not sure she thoroughly enjoys having sex. I was her first...so she really has nothing to compare to, and i'm pretty average sized. 6.5-7 inches long, and 4.75 inches girth....a little on the thin side. She has never had an orgasm, from me or from masturbating. She says she doesn't enjoy masturbating, but i'm trying to get her to get into it so she can get to know her body and tell me how to make her cum. Anyway, just wondering if maybe im not thick enough to really please her. Any thoughts? Ideas?
