How common is it to get rejected by women as a man?
The most common experience on the planet for men is that one. Including this fun one that happens a lot to most men:

I’ve never understood that but I guess it’s about power? It used to happen to me fairly often, be minding my own business, doing nothing at all. Then, “I have a boyfriend.” Ok, great, who cares. Then I started responding with, “Good for you.” Then after that didn’t seem like enough, I started responding with, “So do I!” to really piss ’em off.
Makes no damn sense how people act sometimes.
