First off, the OP posted on a subreddit aimed towards mentally ill men, posing as "women". There's no "ladies" in that subreddit. As a heterosexual male (an actual real one) I missed the days when gays were fighting to be seen as the same as everyone else, just same-sex attracted. Nowadays you have obviously gay men ashamed of their sexuality & fighting for one male to be seen as a "woman", to alleviate their internalized homophobia.

As far as straight men not wanting a "man" with a vagina? There's no such thing. Those individuals are females hopped on testosterone, who believe they're "men". They're still females, & no I wouldn't sleep with them, because of their desire to be seen as men, as to go so far as to pump one's body full of hormones. I wouldn't sleep with the majority of female bodybuilders either. Guess what, they're still biologically female & trans "women" are still males. Therefore a "straight" male engaging in intimate relations with another male, isn't straight. Doesn't matter if said male pumps himself full of estrogen & inverts his genitalia. From my understanding of the Reddit post from OP, his "girlfriend" didn't even do that & still has HIS male genitalia. Doesn't matter either way, he's clearly in denial about his sexuality & I really wish gay/bi men didn't fight this. You're attracted to effeminate males.
