Try pinging an elastic band on yourself or holding ice cubes

Did you consider a tattoo?

I once saw a really disgusting video, but I think it was real:

(trigger warning: explicit description of physical torture ahead. stop reading now if you're a rabbit)

A girl got her rectum tattoed. Like, right to the inside, where the flesh ends.

It must have been real, because they filmed her face expressions as well, and it must have hurt. I think she shouted, but they dubbed it over with music.

Never seen something as gross like that.

Genitals, rectum and inside of eye-lids.
