Help..

Okay so here is the situation with me, i always wanted to wait till marriage to have sex, i dated my ex for 2years, got engaged I thought he was the one, one day one day we started kissing and one thing led to the other to the point where we almost had sex, we tried it was uncomfortable, it was awkward and im the middle of trying i regret it it before anything else happened, i made him stop and we just never tried again, i was like why not wait.. later on things started going wrong for us, i wasn’t a priority for him I realized he wasn’t the one so our engagement ended...

ive been dating my now boyfriend for almost a year now. When we first met he asked me whAt was my body count, i said one, for the fact that, thAt to me was going very far into what sex was for me..but i never went into detail of how it happened i just said a number. This was never a problem until later on in the relationship he would bring up how it was a bit hard for him to accept the fact that there was someone before him (im not his first, just putting that out there) but the thing is he imagines that I actually went full on sexual w that person and probably that i was even w more people or that it happened more than once.

Which maybe it was due to us having sex for the first time without a condom & early on in the relationship maybe 4 months into it, i loved him everything have always felt right with him, thats why i did it, i knew he was the one since the beginning and i have not regret a thing, i love him so much! But now things are getting more serious and he wants to move in together sometime if things workout for both, so he brought up the conversation again and this time i kind of gave a little more details, because im starting to regret maybe not going into details the first time because he probably thinks it was More than what it was..

it’s important for me to talk about this because if we are going to take things further he either has to believe what i say or do something about it because we can’t keep going back and forth asking about the same thing, because he probably thinks i kept something from him maybe more sex partners which i have not.

What should i do should i go into details? (Hes been with 15 not what i wanted on someone but i love him and i have accepted it.
