Is it normal to watch gay porn, but still like girls?

I'm bisexual, and there's not enough evidence to say you are too. What arouses you isn't necessarily what would satisfy you sexually.

You are bisexual (possibly with a preference for the opposite gender). You simply haven't met the right guy, I guess. If you find men in porn attractive, there can also be men in real life you'll find attractive.

As I've said before, what you watch for porn rarely seems to have any correlation with what you're actually in to.
