Why are (most) men intimidated by attractive women?

Women don't usually get intimidated by an attractive man, they get a crush and it makes them excited no matter their confidence level. For me personally, I'm not overly confident and I've actually be labelled as "shy" my entire life but when I see a hot guy, it makes me smile and I compliment him in my mind lol it kind of makes my day a little nicer. I know that hot guy probably didn't even notice me, he's probably got an equally hot girlfriend and he's out of my league anyway and knowing that, I wouldn't feel intimidated. So saying men are intimidated because she's out of their league or fearing rejection doesn't seem to be all there is to it because it doesn't seem to apply when the roles are reversed in my opinion.
