Can someone help..?😔

Is it bad not to care about sex? I just literally don’t care if we have it or not I’ve been with this boy for 4 years and I know it’s not him I love him with everything he’s my bestfriend, I love having sex with him when we do have sex I’m not like grossed out by him or appauled anything like that I love making him “cum” I just don’t care if I cum or not..and in no way shape or form as I forcing myself to have sex I don’t dread it I kept reading things saying “sex is everything”, “you might not be sexually compatable” “if you don’t enjoy sec your relationship will end” I’m so scared bc I love him so much😢 I don’t want us to end, I just don’t care about having sex.. idk what’s wrong with me or what to do
