There is this guy in one of my classes who sits next to me every class, at first I thought he was just being friendly but a friend of mine told me he likes me and is trying to flirt with me. Now that I think about it, he definitely is flirting with me. I'm a lesbian, I'm not attracted to him. I don't know what to do. What should I do? I never flirt back but he seems persistent on flirting with me.
