Honestly. I get that he’s your boyfriend but you don’t owe him anything. You can still touch and love on someone without touching their butt or boobs all day. But if you’ve been having problems setting boundaries that’s a bigger issue. A real boyfriend would respect your boundaries and if they have a problem talk about it like adults. This sounds like childish and lowkey manipulative behavior. Not saying he’s bad or anything but really childish.
As a guy, I think it’s hard to understand the balance. I’ve never personally dealt with this, and I’m not trying to invalidate your feelings, it’s maybe good to try to be more concise about what you feel. I’m thinking about it now, and if my girlfriend said this to me now I’d probably worry a lot about making her feel uncomfortable. Like it would throw me into a situation of worrying if I’m meeting the right balance
