does it happen to you?

I always hear people (friends) talking about how "great" sex is and that they "can't live without it" and that they "need it", making expression like "omg imagine living without sex?" and honestly, I've had sex a few times in my like, I would say, a lot, lol but I don't think it's that deep, sometimes I used to avoid my ex because I didn't wanna have sex, it just isn't appealing to me, I mean every once in a while I'm like yes, I need to do it, but that could be MONTHS. I think I could live without it. Makes me wonder why I don't crave it as much as other people make it look like they do. Idk is is normal? or no?
