Only like it with him?

Does anyone else only like to do sexual stuff with their partner? As in not even by yourself? I've been talking to my boyfriend and it seems to really weird him out that I only do stuff when I'm doing stuff with him (he watches porn and does stuff on his own and tbh I dont care 🤷‍♀️) I just personally don't have the desire to do anything without him. Before we got together it was crazy, I'd masturbate maybe twice a day because I have a crazy high sex drive, but now I just want him. That's it. Is anyone else like this or am I weird?
