I've always thought that trannys have to have some sort of psychological issues to be doing what they are doing. I know that makes it sound like I hate them, but I don't. Dress up like a woman all you want and tuck that shit, I don't care. More power to them. I'm just talking about the psychological aspect of it.
Anyway, while it would be odd to have a tranny ask me if I wanted some of his/her muffin, I would just take it as a compliment and move on. Gay guys have hit on me a bunch of times when I've been out and I just laugh it off and it's a non issue.
