Am I broken?

Sooo this might be a kinda weird and pointless but I truly do think I’m broken. I am 15 years old, almost 16 and I never have the urge to want to have sex. I’m a sophomore and I’m currently friends with a lot of juniors. They always talk about how much they love sex and give their juicy stories and I just feel so weird Bc I never really feel like having sex or anything like that. Ik it might sound silly but I really need some advice :(
