Mental I think! Always remember woman feel the same way about sexy, handsome men. A lot of beautiful sexy people are not as confident as others may think. Even some of the most beautiful woman are worried about rejection. As an example when a girl comes across a very attractive man. She may turn her eyes away and act disinterested only because she thinks she isnt good enough! Therefore this man that finds her very attractive thinks she is not interested and of course afraid of rejection himself lets it pass with out trying. And vic versa!

It's mental. Some men feel that way because of a fear of rejection. Intimidation stems from a feeling of inferiority. Any time you feel intimidated by someone you view them as superior to you in some way. Think of someone you are certain can whoop your ass pretty good in a typical one on one fight. You feel intimidated because they seem superior to you. It's a big deal for some guys and be a real problem on their social lives. There are men willing to pay very large sums of money to learn how to master their fears and how to successfully pick up sexy women. The best way to get over your fear of the water is to just dive in and get wet. If you're afraid of snakes, people will tell you to touch some snakes, interact with them, once you learn a little bit about them you realize that though some are threatening, most snakes are actually harmless. Once in a while you run into a rattlesnake and you have good reason to steer clear. But, overall, as a whole, snakes need not be feared simply because they are snakes. Most sexy women, er uh, i mean most snakes will not bite you, some may be afraid themselves and try to slither away as quick as possible. But in any event, the more you interact the more you learn and the less you fear. That's how we transform fearful feelings of intimidation that hold us back, into confidence that drives us forward. It stands to reason, women seem to prefer confident males. But, there's a fine line between confidence and cockyness.

women do not know what men find good looking and men don't know what women find good looking

Because you care about how you come across to attractive women. When you are with people that you dont feel you need to or want to impress, you can relax and be yourself. Theres no pressure with no attraction.

It's because we really care about what that girl thinks about us, we don't wanna do anything that would make her think poorly of us. Oh btw she doesn't have to be beautiful by media or most peoples standards, the guy just has to think she is cute/beautiful/ sexy...

Male egos are quite fragile but also very important to them. Any rejection hurts that ego which can leave a guy feeling very down. With exceptionally attractive women, guys pressume there is a higher risk of rejection and tend to steer clear. This is true even for very good looking guys.

i think it's just because they are so nervous that they are going to say something stupid to them.

The answer is: men feel nervousness around very beautiful women for both biological AND mental reasons. I will explain why that is: On the biological aspect of things, human beings tend to pursue mates os simular physical attractiveness. This is because there is far less risk of rejection in courtship, and the relationship will be more sucessful in the long-run. It is simple animal Physiology. An alpha male is better suited for an alpha female, and a beta male would feel inadequate for an alpha female. Cognitively speaking, a man's self-worth is a terribly fragile thing. In fact, men are far more insecure in relationships than women are, because a man faces a higher likelihood for rejection. Also, there is socioeconomic pressure on the man to impress the woman, and there is performace-based pressure on the man to perform for her sexually. If he feels inadequate or inferior to the woman, then it will cause him anxiety. Because of these underlying factors, it is difficult for a man to "be himself" in front of a gorgeous female whom he wants to win-over. It should also be noted that men cannot handle stress as well as women, hence why they may crack under pressure and act like idiots in front of females. Oftentimes, women are unaware of what is going on and they can be very critical of the men they are with. The key is to be empathetic with your boyfriend, and to create a comfortable atmosphere for him where he feels assured that you can accept him, despite whatever hangups and short-comings he may have.

Even a man who is normally quite confident may feel nervous around a beautiful woman with whom he desires a relationship. Whenever it is important to make a good impression it will cause anxiety and nervousness. A good example is when a man who has communicated online with a woman for whom he has developed strong feelings, he will be nervous meeting her because he doesn't want to "blow it" and lose the good thing that has developed by doing or saying something to offend her.

I think its just mental, as I blame my crazy head for how I overthink things and get scared by those I like.

It all comes down to sex. At the base of every thought process concerning a women that a man does not yet know, is the decision on whether or not he would have sex with her. If a woman is especially attractive there is a certain level of anxiety generated because the guy would really, really like to have sex with the girl, but is stymied in figuring out whether there is a realistic chance, and/or what his trategy should be, creating a 'deer in the headlights' feeling. Some of the anxiety is generated by a feeling of 'depression,'in that he thinks there is no way he'd be able to attract her.

I would agree with mental. The reason being is because I feel with male or female, when they are with someone very attractive they feel either they are non-deserving of said person; or they feel that this beautiful person has a great chance of hurting them. For some reason, people believe that "prettier people" are wanted more. Which could be true, but there is such thing as a beautiful person with an ugly personality.

It is mental. They fear rejection. I don't know why though because I could be rejected 1000 times just to get a shot with a woman who is "out of my league"...lol What can I say, I like the hot girls. On the other hand most of the meaningful relationships I have had are with average hotness girls, and I would rather have any of them than take a chance on someone I dont know, no matter how hot you are.
