If everyone is told over and over again that they must like spinach or be ostracized, those who have a natural aversion to spinach are going to be ostracized. Making a choice to try to like spinach only to avoid that discrimination is not going to work...it has nothing to do with your personal experience of eating spinach.
But choosing to keep an open mind to spinach out of pure scientific curiosity might be more successful. Again, the choice to keep an open mind is just as valid as the choice not to. But I still believe it is a choice...maybe not at first, but we all have our opportunities to attend a buffet if you will.
To translate, many gay men try forcing themselves into liking straight sex for the wrong reasons. This, of course, is going to fail. It comes from a place of self-loathing. Self-exploration is only helpful from a place of self-love, which is a difficult place to find when you are a gay man in a straight man's world.
I refuse to relinquish my autonomy over my sexuality. For me, that means allowing myself to explore sex with women despite my strong natural preference for sex with men. I was terrified by the fact I believed in this so strongly when I was in high school and college. I ran away from it. But by the time I turned 25, I learned to embrace it. Even today, most think of me as a gay man, and believe I am full of self-loathing when I tell them I am not a gay man. But I'm not going to those individuals stop me from...attending those buffets!
In short, I love sex itself more than I love sex with men.
