Um, he's straight because he's into women. Trans women are women. The fact that they were born with male bodies doesn't change that. And this girl has gone to a LOT of trouble to make herself extremely female in every way other than her genitals. It's disappointing to me that so many people put sex with Trans women into the category of "homosexuality." That's ridiculous. I'm a gay man, and I'd NEVER be attracted to a Trans woman...because they're WOMEN, and I'm into MEN.
