You've had very sound advice so far and there isn't a lot I can add other than, trust me I understand your frustration.

I had a sexual partner who had medical problems (very different from yours I might add. Physiological, not psychological) which meant that he could not cum during intercourse at all, no matter what position, how long we did etc etc. As much as this sounds like every woman's dream, it really wasn't. We has fantastic sex, but I longed to be able to please him in that way and while I knew it was not my fault (or his, obviously) all I wanted was to have him cum inside me. It's such a basic human instinct . . .

Fortunately for you, you are not in the same position he is, medically speaking, so hopefully, a change in your medication should do the trick. Be sure to let us all know how you get on.
