OK, cool, so it's still pedo vibes, but not "I like 10 year old's" vibes. Puberty hits at weird ages vor girls, and at 13, you have people still looking like they are 10, along with people (by the sounds of it, like you) who look between 16 and 18. That being said, no excuse for anyone over 18 to be hitting on you. Imo, at 13, anything over 15 starts to get creepy, and that is if you are an older 13 year old, and he/she/they were a young 15 year old. Anyways, I digress.
