I think I was also arouse because of the story. In most of the movies the transsexuals would seduce the guys into sex. If I picture in my head a transsexual I've seen in a porn movie I will get a very hard erection.
What if I like Transsexuals? Would this make me gay? This is bothering me a lot because of my religious beliefs as a christian.
Male / Female Sexual Behavior-
I read this article. I don't think any type of activity in the article makes someone gay or straight. A woman can finger a man's ass and that would not him gay. A woman can finger her ass and this does not maker her a lesbian nor a heterosexual.
