I'm a guy who doesn't find fat old hairy guys at all attractive, and who is turned off by older guys who shave everything, trying to pretend that they are 14 years old twinks again. That said, you are an 18 year old hairy twink. Your hair is kind of cute, a bit premature as far as I'm concerned. I say shave it, go back to the little boy look because you can get away with it, and have fun, since you are an (almost) little boy. If you hate it, hair grows back. If you like it, have fun. I'm also guessing that you have a really hairy nut sack. Shave it! Feels better and looks a hell of a lot hotter. But don't touch a hair of your boy bush. Guys should all have a hairy dick, especially if they are uncut.
Cheers.
