Actually I'll exclude the guys from this because I've seen a wide range of guys from unattractive to very attractive doing this...
but it seems like only attractive girls post those kinds of questions. They know they're pretty and they know most people will say they are so why do they need to ask? Maybe I am jealous (well I know part of the reason is because I'm jealous).
The girls you truly think they are ugly aren't going to post any pics (even if they're not ugly). That's how I see it.
All of my topics get 1-2 stars but a ton of people always answer (especially the 1 star ones).
Honestly, I've seen girls who were not that attractive post pics.
But the vast majority who asks these questions are a little above average looking, they just want to see how much better than average they are. The ugly ones, and I'm not trying to be cruel, are ones that are NOT going to be asking 'cause chances are, they already know. the majority of them, I think, are really just fishing for compliments so I never even bother to read those questions.
But yeah, some guys on here who are average looking are...eh. I'm not gay, but I can sense attractiveness of my gender. THEY should be the ones who are asking, not the attractive ones.
Sometimes they really, really don't know if they're pretty, even if a million people have told them, and will never think they are, no matter how many more millions tell them, unless they experience a real psychological breakthrough. Sometimes it's an ego thing.
I think it is probably a self esteem thing. Even the prettiest girls will sometimes doubt how good looking they are, and posting pictures of themselves and getting positive comments is a good way of reaffirming it. On the other hand, girls who aren't as good looking may not want to post pictures because they would rather avoid risking the possibility of comments that tell them they don't look good.
Everyone sees themselves differently than everyone else, even the most beautiful girls in your eyes may have the biggest doubts about themselves. One girl I know who everyone adores is called ugly by her mom. She isn't, she is by FAR from ugly, but she does believe it. She's heard it so much that she's believed it.
Often though it is a self esteem issue. As I said everyone sees themselves differently than other people sees them, and having pictures of themselves up and getting comments denying that they're ugly cheers themselves up. It's not that bad to have a bit of a boost when you're feeling down, but for me, I hate the attention.
