If "tranny" means transexual, it probably doesn't go with being "perfectly straight."
If it means "transvestite" so far as I know they aren't in the LGBTQ or whatever it is yet.
If you ever did a guy, and youre a guy, youre a homo and thats that.
So then it isn't a choice?
I meant transexuals, and by “perfectly straight” I mean they are sexually attracted to and carry on with the opposite of their biological sex. Of course they may so butcher themselves as to render normal straight intercourse impossible, but they’d still do whatever it is they do with the opposite sex is the point.
