Teen sex

Me and my boyfriend have been dating for 3 years already. I’m 18 and he’s 17. It’s been 3 moths since we’ve had sex. And I don’t know what to do I still love him and he still loves me but is it normal to just not have sex for 3 months? We use to do it all the time and now it just feels like we don’t even know what that is anymore... Idk what to do someone help me 🥺
