Why is it wrong for a girl to be sweaty?

TubaQueen • Roses are red, Tulips are too. If you don’t wash your hands, I’m not chilling with you.

Ok, so obviously there’s nothing actually wrong with it, but why do people react so strangely towards a girl being sweaty or saying she’s sweaty? And that includes the sweaty person themselves. I said I was hot and sweaty once because it was HOT outside and I got looked at strangely. And if a girl has sweat stains/marks on her shirt it is usually embarrassing and weirdly treated. To contradict this though, I‘ve seen plenty of guys have sweat running down their face/neck/back/etc and no one says anything. It is perfectly acceptable. Maybe gross to be around, but acceptable.
