Ya got me wrong, buddy, I'm just talking about semen in general, not seeing a TS, to me, they're just chicks with dicks. I've been with one before, although it played out more like a male-female encounter, the thought of being passive just doesn't do it for me.
Basically what I'm saying, if I pulled a TS in a club thinking she was female and found out she wasn't, I'd still have sex with her, infact my one TS encounter was probably the best sex I ever had!
Do it, whether you want to be passive or active, just stay safe!
