How many transgendered women or crossdressers have I seen at straight bars?
Zero. Never. Never ever. Not once. Not even suspecting once.
How many trans women or crossdressers have I seen at gay bars?
Plenty.
My point being, you literally have to go to a LGBT bar or something to even have a chance at "accidently" picking up a tranny. It never happens like accident and even then, it is very very obvious 99%. The guy had regrets after getting blown for 9 minutes. Not that he didn't know. If he didn't know, he should have been asking based on where they met. If you are picking up a tall lady or a lady with big hands at a gay bar, you probably should be asking questions if that ain't your thing.
