This might be a bit of a weird question.
So I've always been under the impression that in a good relationship you pretty much know everything. Not in a controlling way or anything, but more about having a solid friendship base within the relationship where you know everything about each others past, basically I liked the idea of knowing each other inside out (to a certain extent). I always thought that knowing about each other's sexual history and relationship history was somewhat important. It's probably the only thing DP and I don't know about each other.
My ex and I were together for years and we knew everything in that sense, who we'd both been with, about past relationships, everything - but we were fairly young and there wasn't a lot to tell and it all kind of just came out casually when there was a lot of security in the relationship so I wasn't bothered.
With my current DP, we know really little about each other in that sense. I know about his one long term relationship and he knows about mine but that's it. Couldn't tell you even approx how many partners each other have had, if we still have contact with anyone we've slept with, when we lost virginities, nothing. I'm worried that it's weird to have this part so untalked about in a serious relationship but also feel like it'd bother me to hear about it.
Am I overthinking this?
