This guy should have just laughed it off with his buddies. Being tricked by a transvestite isn't the worst thing that could happen to you. Just get over it. That's what a real man would have done.
But instead, it will be she-males in the cellblock for the rest of his life.
A real man would not be picking up teenaged strangers to have anal sex with them at parties. Real men do not get "tricked".

The fact that he overreacted as strongly as he did suggests to me that there was more going on than we know. I'd guess that he "knew," and was only OK with it because everybody thought he was with a female. When "she" was outed as a cross-dresser, he was as well. We're dealing with Latino culture here, remember. Homosexuality would be a big problem, hence the cover story. He had to kill "her" to keep the truth from coming out.
This explanation makes sense to me. The killing doesn't, though.
What ever If I were on a jury I would turn the killer loose.
