Simple. I like the power dynamic.I'm sorry, but how can you be straight if you like anal scenes between two guys?
Would I ever have sex with a man?
No I am not attracted to men.
Do I enjoy watching dominating sexual encounters?
Yes.
Therefore if a man tops another man it is a power play therefore it appeals to me.
Do most guys like anal? No. BUT it is a power play to do anal because so many consider it a form of dominance.
Does that make sense? Taboo appeals to many as well.
Sexuality and fetishes are strange right?
