Filming yourself

So I’m a hormonal (legal) teenager and sometimes, when I’m alone at night and just jerkin’ the gerkin’ ain’t quite enough for me, I film it and post it online. In the moment it feels like the hottest thing ever that girls on the Internet are looking at and commenting about my body, but after a couple days I usually get this sort of guilty (for lack of a better word) feeling and take the video down. Am I weird? Is this a common thing or...?
