What in ballbusting turns you on?

I'm very new here. I will share the back story on how I got here.

I usually go on omegle. I find soo many perverts as usual but this time, it was MUCH different than I thought it would be. I usually skip these type of men but it caught my eye. He was indeed naked but asked me a weird question, do you want to pop my ball? I didn't understand anything but I still replied with"sure" . He gave me two options, crusher and needle. Again, I was confused and said needle. He brings a big needle and sews it through both balls like kebab and starts swinging his balls. I was very confused and was just laughing at everything he's doing.

I wanted to know more , I searched it up on google and found some gory stuff. I didn't really hate it, I was just fascinated that this can turn people on. Some of these stories go against everything my husband would want to do lol but it's kinda interesting.

But I still want to know how this turns you on, it's just blatant pain isn't it?
