In my case, that isn't even possible. You saying look at that hot girl is the same as saying to me, look that is a nice chair. No sexual arrouasal for me at all. A hot girl in college liked me and she stripped and asked me to feel her breasts. I felt them, then said "nope, nothin!"
I had a friend in college who was attracted to trannies. He is from the islands and culturally, it is not acceptable to be gay or bi. He is bi but would NEVER admit it. In his head he is "straight."
How we found out was a group of went out to a gay club and low and behold this guy straight guy starts talking up a trannie. He kept saying *she* is beautiful. We all kept telling him, THAT'S A MAN!! About an hour later we're looking around and can't find the guy or the trannie. He went home with *her.* The next day I went and asked him what happened. He admitted sleeping with *her.* He said *she* warned him what *she* was and told him she wouldn't let him see *her* penis. So he did her while *she* kept something on. Damn near every week he was back at that club.
Guys like him are bi but are so in denial they think by being with a man that looks on the outside like a woman, it makes them not gay, or less gay. "It's looks and feels like a woman so I'm not gay!" Were his words. Trannies go for guys like him.
