I guess it's because they either had a tough childhood or they are just born shy.

Perhaps they don't know that they're attractive, or perhaps they were ugly ducklings who were constantly taunted for their ugly looks and despite blossoming with age they carry the mental scars, and inside still believe they are unattractive.

Don't know. Never been an attractive guy. Let's face it. Women can be pretty demanding, mean, and unclear in what they want. No one wants the ego stepped on all the time.

Yes it is very possible. Attractive guys are most likely to become models/actors. The ones that have no confidence with women are used to get what they want depending on their attractiveness and they've met the cold reality that women want even more and so they hide in their shells clueless why they didn't get what they usually get, the way they usually get.

Being attractive does not make you socially adept. People expect more of attractive men. The think they will talk and act like movie characters. This puts a lot of pressure on them. I know a man who is movie star pretty who is so socially inept.

Not all attractive people are that impressed with their own looks. Due to our persistent standard that the man initiate romance, the problem for the man (any man, attractive or otherwise) is more pronounced. I think we must admit (women in particular) that while the handsome prince, unaware of his own "hunkiness", is indeed an intriguing creature, the guy who is convinced he's God's gift to women is despised by most. That leaves a fine line to walk, even for a man who is repeatedly assured of his own attractiveness by women he trusts. Do you think that his not wanting to appear as "God's gift to women" may come off as a lack of confidence? I sure do. This problem is precisely the reason why the idea that men must initiate romance is ridiculous. It has no basis in morality (not that it is immoral) and I would welcome the idea that it is appropriate for a man or woman to initiate romance.

Well maybe because that there not confident so they make them selfs attracted but still feel the same.

Most guys are a bit self-conscious. I have just about no confidence, especially when I'm sober. The evidence shows that if I go for it, I've got a good success rate. I'm told that I'm "not a bad lookin guy" by my friends (which is a fairly good compliment from them) and I know a fair few other good things about myself (which I won't attempt to list =P). However, I also know how crazy, fucked up and angry I am. I know I can be a total nerd sometimes and when I'm in a bad mood I can be a real bastard. I hate so much about myself I actually lose track and remember other things to hate about myself later on. I can't be bothered going into all of that stuff here so I'm gonna stop there. Anyway, I'm on the far negative end of the spectrum when it comes to self-confidence. I kinda know that most of it isn't quite as bad as I think it is, and my good points counter-balance it a little, but none of that matters. I still don't like myself and I struggle to understand why others do. I think something similar applies with these "attractive guys". Basically, they know they're stupid or lazy or boring or something else or all of those things. They don't feel like their looks are enough to balance that out, even if they do realise they are attractive (which a lot of them won't). The reason they have no confidence is that they know themselves and think others won't like them. I know I've probably gone too far with this and that most guys don't actually hate themselves like this, but I'd say that it's possibly a minor version of this. =P

I dont think it is just men. Women who are beautiful can be really insecure as well. I think it is just this idea that we are supposed to fit this one mold when differences are beautiful. Noone wants to be rejected.

Go ask one. LOL.

Girls are pretty scary. They make me all nervous and tongue-tied.

It's possible, that because of the attractiveness, and they "know" they can have many relationships, they begin to wonder if people see them on the inside, and not just the outside?

People are terrible self judges.

They could have been considered one of the "ugly/ nerdy" people growing up.

There are a variety of possible explanations. Just a few off the top of my head... --He had a rough upbringing where the women in his family did not treat him well. --He had a normal upbringing, but it was in a family that did not practice 'concerted cultivation', which is a parenting style that tends to create more socially adept self-assured children. --For whatever reason, his first few attempts at romantic attachments did not work. After a few consecutive rejections, it becomes easy to conclude that one is unattractive. --He has below-average ability to interpret facial cues/body language/social cues. This is more common in men than women and can lead to much confusion. http://www.sciencedaily.com/releases/2008/04/080401081904.htm Again, after a few episodes of this, a guy might conclude that he has no ability to connect with women. ---etc., etc., etc. I'll leave you guessing as to how many of the aforementioned reasons are autobiographical....;-D... . . .

I think it's because attractive people (yes, guys AND girls) know they are attractive, therefore, they feel self-conscious and uneasy when it comes to the opposite sex. Ugly people don't give a damn how they act, therefore, they usually come across as being bolder with the opposite sex. That may be an expression of confidence, but sometimes it can lead them into trouble, and they look dumb tripping along the way. And that's worse, because not only are they perceived as dumb all of a sudden, but ugly as well!

Well it may be because they go out with alot of people, but those people treat them like crap so they think they arent good looking. Ive seen the same thing with women though, pretty women dont have confidence in their own looks because they've been treated like crap by their bf's and what not. Of course theirs an easy way to get around this problem. Do something daily that REQUIRES self confidence, and soon that self confidence can affect ur overall self confidence in everything.

yes

Probably because too many women are way too b*tchy these days. +3
