Birth control or Something Else?

Hi guys I have a question for you all, has anyone ever had sex and not enjoy it?? I have been with my ex for 2 years and within those 2 years we had sex a lot and I haven’t been able to enjoy it at all. So after we broke up I have been dating here and there and been hooking up with some guys I kick it off with and still haven’t been able to enjoy it, now I’m with a new boyfriend of 5 months and still not enjoying it. I don’t know if that’s a bad sign or if it’s my birth control or him I don’t know.
