I'm a 26 year old lesbian. I too sometimes watch gay male porn. Actually, the only porn I watch is gay male porn. I am not sexually attracted to men, but I have my reasons for liking gay male porn. If you haven't already, maybe you should ask your girlfriend to tell you why she watches that instead of lesbian or hetero-porn.

Are you her first girlfriend? Or is she your first? If either of those can be answered with a yes, that might have more to do with your worries than the porn does.

Even if she is just curious, it doesn't have to mean she will act on it.
