Is this a bad idea

I want to ask my boyfriend where the weirdest/craziest place he's ever had sex was. Only because I want to bring up that I want to have sex in this barn.

But I also think I might not Want to know? Because I'll be upset about him having sex with other girls. But I mean, its in the past and I'm Dying to know. But I also get very jealous. So is it a bad idea?

I mean, I got upset that he was keeping his old girlfriends stuff here and that he hadn't changed the sheets since her. But honestly, I'm mkre ok with it now because he's with me and so I want to know kind of. Idk.
