I need advice..

[AllenJoel22]

So everybody at school knows about my sexuality. I tell most people that I'm just myself and that I don't consider myself to be straight, gay or bisexual. Lately at school I have been crushing on this one kid in my grade and I can't tell if he's into me or not. Some days he makes it really obvious, but then other days he doesn't even talk to me. I'm really confused and I don't know what to do. He brags about having sex with girls all the time, but he also jokes around about doing stuff with guys almost constantly. We also almost always make eye contact and sometimes I notice him staring at me. I need advice..
