I'm moving in with my long distance boyfriend next month. We've been together for 2.5 years. He has casually slept with a lot of women in the past and I'm having a lot of anxiety about it....possibly because I'm about to move in with him and I'm scared. I was also cheated on by my ex (we were together for 6 years) and it really messed me up. He doesn't see any of it as a big deal and thinks he was just testing the waters and gaining experience so he could be the best sexual partner for me ( uh huh I'm sure that's what he was thinking 🙄).I know men and women see sex differently and I'm trying to navigate my feelings about this but it tears me up because I've only slept with three men, including him and I can't sleep with someone unless I fully trust them.

If I have children with him, I would not want him to teach my sons to go out and bang anything that breathes.

How do I navigate these feelings gracefully? Has anyone else gone through similar?
