I'm 16 years old and I'm a lesbian. My girlfriend is 15 and we've been together for about four months. She's really cool and I love her alot, but there's this guy at school that I heard thinks I'm hot. I didn't really care, but now I can't stop thinking about having sex with him. Ive never done it with a guy, but I don't want to hurt Missy's feelings. What should I do?
