Can’t deal with my bf’s one night stands and all the girls he kissed!!

My bf was my crush for the longest time... finally we ended up together after dating one time a while back

He had just come out of a 6 yr off and on relationship

During this off times he would have these one night stands (6 to be exact) and he would kiss a bunch of other girls

I’ve only been with ex and never had anything casual or kissed anyone who wasn’t my boyfriend

He came clean on all the things he did bc he says that he wants something with me that would last

But now I can’t get it out of my head

It drives me crazy that he was able to just have sex with some other girls

When I was never like that

He tells me that he’s afraid that I would have this burden and end up looking for these experiences, but that he would rather have me shake if off of me and be open if I want to do it

Bc he wants to stay with me but not if I’m not comfortable

That I want to do it he’ll wait for me

Idk what to do 😔 I really love him and this is the first time I actually want to make this work for the long run

How have you girls dealt with this situation?
