<human>: So I'm going to preface this by saying that I'm very inexperienced at dating.   I've spent the vast majority of my adult life in a long term relationship, and since that ended, I very rarely get hit on or flirted with.  Also I have this problem where I overthink everything.

The Friday before last, I was at a friend's house party.  I met a guy there and after several drinks we kissed for a good long while.  At the time I wasn't thinking I'd ever see this person again, but he was attractive and a really good kisser, and now I kind of want to see if I can actually get to know him.

We're friends on facebook (at some point during the party a big group of us sat in a circle with our smartphones and friended everyone else) but he hasn't really tried to contact me.  Would it be considered desperate or forward to contact him?  I don't know if randomly making out with someone at a party and then actually dating is even a thing people do or not.  Is there an unspoken rule that if you kiss someone you just met, it's automatically a one time deal?  I have no idea what is normal.

Also, if I do contact him, what do I even say?  I feel like "Hi, I enjoyed kissing you that one time enough to want to get to know you.  Hang out with me?"  would sound a bit awkward.  

I'd ask the guy who was hosting the party, but he doesn't know the guy.  He came as a friend of a friend of the host's roommate.  Or something.  Also, one of my girlfriends who was at the party says I shouldn't contact him because she think's he's gay.  I have no idea where she's getting this information, but if he was gay, why would he make with me (who is very clearly a woman)?

Summarize the given text in a few sentences.
<bot>: Kissed a guy at a party, and now I want more.  Should I pursue, and if so, how?
