Is it normal for a girl to watch porn?

Okay, honestly, i'm really horny lately, and i've discovered that i really enjoy porn.... :(

And it's not porn like, guy-girl action, that turns me on, but not that much. It's gay sex, that girl on girl action, and the guy on guy. I find it easier to watch the girl on girl because i have too many guys in my life, though.

I just really want to know if this is normal, because i'm totally ashamed of it....
