So I just recently got with this boy and he mentioned that his first time was a "drunken mistake". It really bothers me that it was just a drunken mistake and I don't know what to do.
Why does it bother you op?
Do you feel like he doesn't place much importance/feelings during sex and takes it as a joke?
Or... is it because you feel he's reckless or what?
If you add some info then we can help
Who even discusses this **** with their partners?
I can get why it bothers you, I always feel a bit weird thinking about my partner with an ex but it is in the past. Think time kind of gets rid of the fact that its bothering you. The issue is there's not really a lot he can do about it, it's happened, I think you just have to think about your feelings and whether you can get over it else it will always be an underlying problem.
He's an alpha male. Deal with it.
