I remember a tranny came on Howard Stern and was talking about how he would take unsuspecting guys home with them and only then would reveal to them that he was a male and they were pissed/shocked at first and swore they were not gay but 90% of them loved the sex and would continue to see him or call him wanting more.
So the tranny wants you to believe.
I've heard from various police officers I know, that they'll go to the local spot where hoes go with the johns. And usually find a male claiming to be straight, either getting sucked off by a guy/tranny, or doing the sucking.
Accounting for some variation in between stories, I'm sure there are men out that that have that fantasy. But I would suspect there is some lying on the trannies, and that percentage is a bit lower. I would make a random guess at 50/50.
There's three sides to every story...yours, mine, and the truth.
