Is she so bitter that she won't allow herself to get over the edge? Does it not last long enough?
What things turn her on in bed, do you know?
I know that HD people place far too much emphasis on the role of an orgasm in the resolution of sex problems....but honestly if you are having sex a couple times per year and she is not having an O, I would think this would color how she perceives the whole experience.
Does she have difficulty reaching orgasm, as a rule? If so I can certainly see why she would avoid it. Might seem to be more trouble than it's worth.
Sorry to throw so many ?'s at you, just found this interesting..
Take care and glad you had a good time! Was the BnB any good, btw?
