<human>: I'm really on the fence about this one. I'm 34m dating a 30f for just over 6 months. 

I used to work with her at another job (I didn't date her then). I left about 3 years ago but she still works there. She's been open about almost everything, but the other day we were texting and I flippantly said, "I don't want to know who you've banged at work". Her response was that she didn't feel comfortable talking about it. I think I had some normal feelings in response to that. 

The truth is I don't want to know details and who because it doesn't matter. The past is the past and I'd just rather not know. After thinking about it however it bothers me a little because a) she hangs out with a LOT of work friends and b) there are some people there that I know fairly well.

I guess half of me wants to ignore it and the other half simply wants to tell her that if it's someone that somewhat frequently see when I hang out with them or if it's someone she hangs out with a lot then I'd rather know. 

I have trust issues (cheated on repeatedly, haha) and I know there's  danger that it will make me feel pretty uncomfortable. What I think would be more upsetting though is finding out down the road. I don't want to be in the dark about her previous relationships with people she frequently hangs out with (or that I do too). I don't want surprises and want to know who it is I'm with.

Can you condense the text into three sentences or less?
<bot>: I am aware that sexual history is a private matter, but should some of that be disclosed when there are mutual friends?
