<human>: I've been dating/seeing this girl for 7 months now and there are strong feelings involved. I'm 23 and she's 21. 

The problem is that all her close friends are basically guys and something sexual happened with almost every single one of them. She slept with a couple of them once or twice EACH for "fun". One of these guys would come over to her house to hang out with her basically all the time. Another confessed his feelings for her, but when she rejected him, he got butt-hurt and said he didn't want to talk to her anymore (this was when we first started out). Recently, the same guy's been hanging out with her at the pool or at some events around town.

Worst part is that, I'm not her boyfriend. So I can't really say that I'm not comfortable with her hanging out with these guys so much. 

What do I do? I don't even know if we'll ever get into a relationship, but it just frustrates me that she's around guys like that.

Can you give me a shortened version of the text?
<bot>: casually dating girl who has had sex with close guy friends that she still hangs out with. Not her boyfriend, can't say anything.
