Why are so many men kind of ugly?

I know this is a weird question, but I’m a girl who’s both attracted to men and women, and I feel like guys are a lot uglier than girls on average. I know that women are usually treated with higher standards than men when it comes to beauty,(Weight, makeup, hair, etc.) but I don’t understand why it’s so different between genders. When I see famous male celebrities that are supposed to be attractive, I usually think they’re okay, like a 6 or 7. But even day to day women seem a lot more attractive, never mind celebrities! When I think about a girl who’s “okay” appearance wise and imagine her as a guy, the guy version seems especially attractive while on a girl it’s not. Am I just biased? Or is it just harder to be hot as a guy?
