Hey, I've currently been going out with my current GF for over half a year now, and things are pretty awesome and I enjoy the sex but there is one outstanding issue. My girl does not orgasm or finish/cum in any way shape or form. During a nice session of sex, she enjoys herself but claims it gets very sensitive as it goes on. She says it feels likes she needs to pee during sex at times as it gets more immense. During this period she clenches her her vaginal muscles as it gets sensitive and it forces me out quite often. She claims she enjoys the sex and there is nothing to worry about, but it sucks knowing I can't finish her. Can anybody shed any light on this? Any personal experience with such drama? Without sounding like a big head, I have a big penis and have never had such an issue in the past.
