<human>: Summarize the given text in a few sentences.

My boyfriend and I have been dating for six months. Before him, I'd had two relationships, both lasting around 2.5 years, and I'd never had any sexual encounters with anyone other than them, or even kissed anyone else for that matter. 

We met on Tinder shortly after I broke up with my ex-boyfriend, hit it off amazingly, and ended up having sex on the second date, (which was probably a mistake, but I had previously been in a sexless relationship for nearly eight months.) That weekend, I for whatever reason asked him to be my boyfriend and he accepted reluctantly. The first couple months with him were a bit awkward for that reason, but we continued seeing a lot of each other fell in love quickly.

Fast forward to now, I have told him that he's only the third partner I've had, and he's told me a bit about his more serious relationships, (not even disclosing names mostly), but I couldn't even ballpark how many girls he's been with. He's a very handsome guy as well as confident and free-spirited, so I imagine that it's a lot. He has hinted that he has been promiscuous in the past. I only wish I'd inquired more before I was so emotionally invested.
 
Why does thinking about this make me uncomfortable? I know it doesn't matter, but it bothers me that I don't know. I love him dearly, how can I approach the subject without hurting him or myself?
<bot>: I was pretty sexually inexperienced before meeting my boyfriend, he has told me little about his past experiences with women but part of me feels like I should know even if it hurts.
