Are you actually comparing fucking leggings with skinny jeans? Leggings have a thin breathable fabric. Jeans on the other hand are thick, rough, stiff workwear. They don't bend with your movement as much as a paper thin fabric of leggings, and constrict your blood vessels and nerves, making them uncomfortable, especially in the groin.
Your balls aren't meant to be packed tightly in a thick fabric. This isn't some CBT S&M session. That fucks up your testosterone levels, sperm count and even the balls themselves from too much pressure. No wonder millennials and zoomers are low T, because they've been wearing these CBT jeans for half or most of their lives.
