<human>: Give me a shortened version of the text

I've been with an amazing girl for the past year. We're moving in together this summer (both of our first times) and I can see myself being with her. We get along amazingly. I love her. She's 26, I'm 27.

Now my question... I keep thinking about this one thing. I can't get it out of my head, and I'm wondering if I should sit on it or bring it up with her. Basically she told me way back in the beginning that prior to our relationship she'd been to a sex club a couple of times. I really have no idea what those places are like, who she went with, and what happened when she was there. Half the time I think about it it's super hot, the other half it's intimidating and a little squicky. I also have an inkling that she went with one of her close friends.

So far this is a pretty stupid/simple question. The problem is that I tend to get jealous, and prior to this I was in a toxic relationship with a lot jealousy back and forth. So while I'm aroused/intimidated/squicked, I'm also not sure that I want to know the details. I don't want to go back to those feelings I had in the toxic relationship, where I obsessed over details of her history long past.

I know this sounds a little silly, but I'm really confused as to whether I should ask her about this or let it be. I'm usually very pro-leaving-the-past-be, but I can't get this out of my head. It's at a point where she notices I'm a little off and asks what's up. I don't really want to be in possession of sex club details ("oh yeah, I gave my friend a blowjob while 8 dudes watched") that I can obsess over. That said, in the absence of information I seem to be obsessing over it. What would you do?
<bot>: Year-long relationship. Girlfriend attended sex club a few years ago. Can't stop thinking about it. Have a habit of obsessing over details. Should I let it go or ask her about it?
