Most Helpful Girl
Well, a lot of really good looking guys are too obsessed with looks and it gets old. Some of them are actually insecure about themselves and fill that gap with their outward appearance. Not all are like that, of course, but many are. Sometimes they can be intimidating, in the fact that I often felt more judged by some of them. It is like they have this weird, unrealistic checklist of what they want in a girl.3

I guess it depends on how the girl looks?
If she's not that extraordinary-looking, then chances are she'll feel intimidated.
If she's extraordinary-looking and she knows it with not hints of any doubt, then chances are she's not likely to be intimidated.
If she's extraordinary-looking and she's vaguely aware of it to some degree, but still has doubts here and there, ... well, when a guy like that walks into the picture, that's the key defining moment in her life when she's going to be driving her own self crazy on questioning herself and judging her own attractiveness and value.
If she's below average-looking, then fuck that egotistical narcissistic self-absorbed asshole... he probably wouldn't make a good boyfriend/husband anyway.
In my experience, when men and women come to the bargaining table to negotiate (i. e., a date), the feeling of "intimidation" kicks in when two things are true: (a) we really really want what the other person clearly has to offer us, and (b) we are unsure about whether there is enough value in what we have to offer to entice/induce the other person into voluntarily giving us what we want.
So, it really depends on what girl is sitting on the other end of that table.
All else constant, however, if the guy is a 9/10 and the girl is a 9/10, and they're both 23 years old, just barely out of college and starting their careers and lives, similar personalities, etc. ... the girl's "opportunity cost" is higher, even if the guy across the table doesn't value what she has to offer that highly.
In the general marketplace, sex with a 9/10 23y/o female is more valuable to the general population of men than sex with a 9/10 23y/o male is to the general population of women.
So, in terms of the relative value of what they're bringing to the table... in a theoretical academic world, if this were a hypothetical bankruptcy liquidation and they both liquidated the value of their respective looks into cash, she would have a lot more cash on her end of the table than him.
The reason she may feel intimidated, however, is because she still wants what he has, but she also knows that she doesn't have the same bargaining/negotiating power with him compared to a 5/10 or 7/10 guy. So, she's trying to figure out alternate ways to bargain and negotiate with him that won't insult him, and are vastly different from how she bargains and negotiates with the men she usually dates.1
