For me, on the other side of the coin, my 10% straight is for a few reasons. I had relationships with females all through highschool and was sexually active with most of them. The sex was good, it got the job done and I wasn't turned off by any of it. However, I was not nor am I attracted to females in that way. I don't desire them sexually. I can appreciate beauty in a female and there are women I find gorgeous but it pretty much stays at apprecition. Also, I was never emotionally attracted to them in that way. I loved the girls I dated and slept with but as friends. Does that mean I won't ever sleep with a female again? Who knows? It's not something I have the desire to pursue but if the situation is right, I'm not going to rule some activity out. Also, I have a huge attraction to straight or "mostly" straight guys and one of my fantasies is to be with a guy and a girl. In that case I'm sure I would completely enjoy all aspects of the experience. Hopefully, there would be at least some minor interaction between me and the guy, being he would know my preference. Even if there wasn't though, I am such a voyeur and the thrill of being able to share in the experience with him, would totally make me open to anything. That's my explaination.
