Is it normal to want bang people you argue with a lot...?

Okay, so I'm 18, almost 19, and I graduated last year. I have some really close friends, they're basically all male, and one of them is 16 turning 17. Never before have I ever thought of any of my guy friends romantically because this group of friends isn't something I'd want to make awkward and I'm the only girl among our entire friend group. I've only ever had sex with one guy, and it was my first boyfriend, but we broke up this year.

Basically, this guy that's my friend is younger so he's still kind of arrogant and thinks he knows everything and he and I fight all the time. Like, it's kind of a running joke that him and I just bitch at each other all the time because he thinks he's right when he's not and he just loves to argue and he really frustrates me.

But he and I always have had chemistry, especially when we argue. No one else has ever noticed or suspected because they just assume he and I hate each other mostly, but it's like when I'm around him my body is just electrified, mostly because he pisses me off but also because when I'm mad at him all I can think about is seducing him. I don't know why, I just always had that image in my head.

Well, a while ago all of my friends had a big bonfire where I got slightly drunk and so did he, and he and my other guy friend came to crash at my house. I left them both to pass out on the couch, went and brushed my teeth and got ready for bed, walked into my room and he was laying there on my bed looking at me and we just instantly started making out and it was like one of those moments where we both knew exactly what the other one wanted and he was an awesome kisser so one thing led to another and we ended up having sex. When we were done I'm like "Maybe you should go back out to the couch now" and he said "I think it's a better idea if I sleep in here" and he slept on my floor, I'm assuming because he didn't want to go back out in case our friend was still awake.

Ever since then, nothing has been awkward between us. None of our friends know or suspect anything and we act the same around each other, it doesn't feel weird. But now every time he and I argue it's like I want to have sex with him even more. I don't know if it's some sort of psychological way I'm trying to get revenge on him or something. I don't want to date him and he doesn't want to date me, and his Dad might be marrying my Aunt which makes this kind of weird since he'll be related to me someday probably. is it normal to do this?
