I know this may sounds like commons sense and it may sound like a silly question, but sometimes I have wonder how do you know if you are good looking or not. Even if you think you are good looking, you may not be good looking at all; or the opossite is true as well. Something random that came out of my head waking up at 7 in th morning.
Get on chat roulette and just have girls rate you one after the other xD I did that once, stayed in the range of 3 to 7, even got an 8 once or twice. OK, that's kind of a ridiculous range I know, but it just shows you that everyone thinks different people look sexy in their own ways. A lot of guys don't like girls with glasses or braces, but for some reason I get turned on by that! (im a natural nerd lol). So like what RimandLea said, you can't just hear "Youre good looking" or "Youre ugly" once and decide that that's what you are, that's ridiculous. Don't listen to people that say you're ugly, that's just something America uses to put people down and try to keep them in their place. F*ck that! Do your thing bro! :D
if you get complimented a lot on how you look? or if people tend to stare a bit at you. I've been told I am good looking - but honestly I don't care- I'm not a model so why should i? I mean looks fade as time goes by - but I think we get more beautiful when we age , it shows character and that you have lived life.
if you spent your day going around thinking I'm Beautiful or good looking , you are not doing much for yourself there's a fine line between being cockey and having low self esteem.
