So there is this young 22 year old I met ( I'm 29). Number wise she is honestly a 8-9/10 . We were both looking for a fwb (though I'm generally open to more nowadays).

We texted for a couple weeks, met slept over and it was great. More of less we text back and forth every other day and I see her about twice a week. We bang the shit out of each other , have some food. She is leaving to join the army in a month and though it may be my mistake I've invited her to do different things, which we haven't done.

We kind of chill besides just banging so I figured if there is fun shit I'm doing in the city before she goes why not invite her. She keeps bringing up about how she could absolutely not care if I was sleeping with other people or had a gf or this or that. I think she's pretty cool , the sex is mind blowing, and I think that if she wasn't going to the army I'd be down to chill with her more (out side the bedroom too). I wasn't really sure if it was defense mechanism or if she really doesn't care, which if so is kind of a turn off .

I'm gonna enjoy it while it lasts but my issue is that shes going out of town for a week, and I know she'll probably hook up with guys. While I talk to other girls the guy in me is slightly jealous but I am mature enough to be over that. My issue that is my main question is how do I broach the subject of sleeping with other people without looking needy or like I am suffocating her. Personally if if I'm going down on a girl , Id like to know safety wise how many other people are touching that area.

Thoughts?
