I have been having sex with my boyfriend for over a year and have yet to have an orgasm. I can have them from him going down on me and from masturbation. When we have sex, the greatest sensation I feel is the need to pee. I heard that this can happen to a woman before she orgasms, so we have continued sex for long periods of time during which this sensation does not go away and I never orgasm. It is extremely uncomfortable, not pleasurable--like being on a long car ride, drinking 3 cokes, and not being able to pull over to pee. I've tried getting up in the middle to go to the bathroom and I can pee only a little. I am certain that I do not have a bladder infection. I could stand this if it actually led to an orgasm, but alas, this is not the case. Any advice is appreciated.
