Once I had a guy patiently try to explain to me that the reason men sit like this is because in the summer it’s very hot and it’s dangerous for them to sit in ways that overheats their testicles. It could cause permanent damage! So, it’s not their fault, not really, that they take up twice as much space as everyone else. They pretty much have to sit like this.
He seemed a little nonplussed when I wasn’t immediately sympathetic.
I was innocently scrolling through Robot Hugs, a truly excellent webcomic, when I stumbled upon a very apropos entry. According to this story, it’s not the size of the balls but the hot hot heat? Interesting. And not entirely convincing.
