Why are teens so perverted?

like they(boy and girl) go crazy when they see someone with a big butt and it makes me feel uncomfortable thats why i where my uniform or loose jeans because i feel so exposed. i feel as if everyone is trying to imagine me naked for some reason. they act as if they never seen breasts, hips or a butt before and once they do they just interested in talking to you all of a sudden and it makes me want to punch them in the face. i dont even dress like a whore but i do try to dress nice, i simply wear a graphic tee with skinny jeans and suddenly people are talking about my *** and sleeping with me
