My situation is not as pronounced as yours, but I learned at a young age that I was capable of having relationships with both men and women. My first sexual relationship was with another guy. Other than with my wife, I've had 4 times more sex with guys than girls. But there was a time when I met my wife that I knew she was "my person", irrelevant of gender, she was the "one" I love and that I wanted to be with.

Years have gone by, and my sexual preferences have changed some. I definitely prefer men over women, masturbate almost exclusively to gay sex. We don't have a lot of sex any more, maybe 3-4 times a year. I was satisfied in the past with our M/F sex, but she was the one that stopped and in the absence of any sex, I have filled the void with my fantasies and desires.

It is refreshing (still unfortunate) to see that women can be in the same sexual situation that many bisexual married men find themselves. I've read your post over a few times and I feel that like any life choice you will have to balance the impacts of your decisions. In my case, the positive life benefits I have being with my wife and kids far outweigh the momentary exhilaration and pleasure swapping semen with a hot guy. You have to dig deep and find what you really want and what will fulfill you most.
