BUTT pain for sympathy

Okay so I have googled this and found a podcast and some other forums where people ask the same question so I know at least that I am not the only one but I can’t find any legitimate answer.

Last night for example I was watching a video of someone stretch their ears in the worst way you can stretch your ears. Just SHOVING gauges or whatever theyre called in the ears bigger by bigger until the guy got his desired size. Caused an immediate blowout so from that moment forward his ears looked like sad buttholes. It was freaking terrible and the guy didn’t even move.

Anyways, watching this made my butt hurt. Anytime I see someone get injured or hurt, my butt hurts so bad that I clench my butt cheeks.

Can anyone tell me why I feel sympathy pain IN MY BUTT CHEEKS 😂
