Ok. Very strange thing going on. I just recently got back together with an old flame - ex-girlfriend. We dated for 3 years about 3 years ago. During our first try we had a pretty active sex life. nothing crazy, just regular happy sex. We were both able to finish and everything was great. So now we've been re-dating for a few weeks and have gotten hot and heavy. I've been able to satisfy her at least two or 3 times a night. Problem is, no matter what she or I do, I can't finish. And she's trying really hard. In fact she's gotten a little more sexual and talks dirtier and is much more enthusiastic about everything. I'm not sure what to do. She's getting a little upset because she thinks I'm not attracted to her.

I know this is kind of vague but any advice would be appreciated...
