So fucking confused about this (gay?) guy. Please help.

Here is my story. This boy is driving me nuts. I met him in a school end-of-year party. I am 16, openly gay, tall and slightly chubby, nothing special. He is 16 and tall too, slim, and mad about his personal image. I knew he was kind of openly gay too, so, he was one of my very few chances of meeting someone without recurring to gay hook up sites. Well, we start talking about guys in the line, Justin Bieber, One Direction and shit. He makes a few gay jokes here and there, I decide I like him. We start chatting next day. He doesn’t talk about gay topics, he says that all girls are sluts, and that’s the reason behind his homosexuality. We don’t stop talking. He talks about girls on a daily basis, but I’m slowly taking him to the point I want, us. He sometimes says “We should kiss next time we hang out” I say “Yeah, no problem”, when he uses “Suck my dick” I’d respond “You wouldn’t even dare to try my blowjobs without going mad” I feel kind of slutty, but I’m telling this shit between jokes, but every time I try to get serious, he takes the conversation to another path. But this weekend, we went to two different parties, he kissed 7 girls in his; I got drunk in mine, and sent drunk texts. “If you weren’t my friend I’d kiss you” and shit. So, now we are like, talking some serious stuff, he asked me for a kiss now, I accepted. He wouldn't stop asking about what my girl friends think about him, who is a virgin, and that gay friend-hetero relationship stuff. I’m trying to clear my doubts about his sexuality, and I don't want to force him into nothing, I don’t know if I should fall for him, if I’m his crush, his slut or his gay friend. It fucking confuses me. Why’d he say he is gay when he kisses and is attracted to girls? Why’d he sometimes respond to my innuendos? Why’d we haven’t stop texting each other?

TL;DR: I fell for an openly gay guy, who turns to be somewhat a bisexual, who flirts with me (maybe), but is attracted to girls, but happens to be that he is kind of misogynist, and I’m totally confused.

PS: Sorry for my bad grammar, English isn't my first language.
