What kind of guy happens to take a 10" knife with him when meeting his girlfriend at a hotel, staying 23 minutes and stabbing her 110 times? A premeditating murderer guy
You don't know I'm Gay unless I tell you, or act like the stereotype to make you feel more comfortable (other Gay people know exactly what I'm talking about).
I could imagine a post op transexual, who has legally been declared a woman, feeling she is a woman and has no need to tell anyone any different. On one hand I agree with that unless it's becoming a serious relationship, but then you're in more danger. But if you say upfront the guy sees you a certain way.
I could imagine a pre op transexual having guys fuck her ass and trying to pull it off as her pussy, that's selfish, dangerous and wrong.
