I'll tell you my opinion about this first, and then I expect to receive opinions from you all.
My opinion is, society wrongly equals someone being feminine to someone wanting to be taken sexually, as a woman. Society considers it is impossible for a "feminine" male, to act and function both socially and sexually as a male. They always associate wanting to be beautiful and sexy, especially by wearing "prohibited" women's clothing, to liking men, as well as wanting to act and feel like a woman all the time (much less of a "real" man, but "acting" as a man for social convenience, for power and position).
And I say this by experience, because I've had a couple of girlfriends in the past that thought this way even though they clearly experienced my maleness, by having sex with me when we both were super-sexily dressed in lingerie. They always thought I liked men and I was a bisexual but didn't want to admit it, for fear of being discriminated against by society.
What do you people think?
