Is it normal that i think about having sex with a girl so bad?

I've been having these feelings. I find a girl's body very sexy and attractive that it makes me wanna have sex with a girl. I'm a girl, and a guy's body has nothing on me. Even normal porno has nothing on me. But when I see two lesbians together, it makes me horny and I wanna touch or kiss them sooo bad. What can I do?
