<human>: Give me the gist of the text in a nutshell

I've known her for about four months. Within the last few weeks she's gotten really flirty with me, but not really on a regular basis. She'll sit on my lap, lightly touch my face as she passes me, hold my hand, call me "bae", things like that. I reciprocate a lot of the time, but I'm not as smooth as she is, so sometimes I just kinda let it slide.

She's kind of a flirty person, so I can't really tell if she's directing these actions at me specifically or just guys in general. For example, I've never seen her sit on another guy's lap, but I'm sure it's happened since we've met. She's a real party girl, and engages in drunken adventures with her friends pretty regularly on the weekends.

We've hung out a few times, and she'll tell me about these "super attractive guys" that she met at a party last weekend. I've narrowed this behavior down to two possibilities: She has no interest in me and just likes bragging about meeting good looking guys, or she brings up these other guys to make me feel jealous (if this is her goal, it works). I don't know for sure though, could be wrong on both counts.

Sometimes I feel like we have great chemistry and really like each other, other times I feel like there's nothing there.

Could this be something real? Is she just using me to boost her own self-esteem? If this is worth pursuing, what is my next step? Should I have masturbated before writing this post? Probably. But whatever. I'd really appreciate any help.
<bot>: Recently started crushing on a girl who likes to flirt. Can't tell if her flirtation is directed at only me or other guys, too.
