Everyone is bisexual sounds very stupid, and very similar to political lesbians "every woman is lesbian, but forced into straight marriage", when it is just not true.

There are a lot more bisexuals than homosexuals, that is true, but homosexuals and heterosexuals aren't "fluid sexuality and just bisexuals in denial" even without society pushes. It would be really great to actually be able to be fluid or change your sexuality - it would saved me from so many problems in my life. However, it is just not possible.

My example should be a good one, I think. I was married on a man by my own choise and without any pressure outside, I wanted to become straight and to be normal like everyone. I really really tried to be aroused with him in a bed, we tried everything, but nothing worked. Even when I was wasted or with "arousal enduring pills", I would think about women or start molesting women - even when my brain is shut down. I can not make my body enjoy men, even if I really want and try everything. While being with women does not need anything, I am aroused very easily by women, just scent is enough. And I did not know anything about homosexuality back then, I did not know any homosexual people, I did not know that it is possible for two women to be together - so it is just body working on its own. Biology does not care about society and social pressure.
