Okay kiddo, this topic may be a bit confusing for someone your age, but I'll try to explain it in a way that you can understand.
Erotophilia is when someone feels attracted to or interested in sexual things. It's not just about liking someone romantically, but feeling the urge to do things of a sexual nature with that person. Sometimes people just feel this way naturally, it's not their fault and it's not a bad thing.
It's important to remember that people have different levels of erotophilia, and that's okay too. Some people may feel the urge to do sexual things more often than others, and some might not feel it at all. Whatever your level is, it's important to always make sure that you're respectful of yourself and other people, and that you never do anything that makes you uncomfortable.
So, to sum it up for you, eroticophilia is just feeling attracted to sexual things and it's okay to feel this way as long as you're always respectful and safe.
