Apologies if I'm wrong, but ... Cock and ball torture? ...
Well, I wouldn't have been able to do that, being a girl. I have tried self-inflicted nipple torture in lieu of more dangerous forms of pain, but I just didn't gain the cathartic result I wanted.
I think it's usually better to figure out where your emotional pain is coming from, and treat that, than to ignore and bury it in layers of alternative (physical) pain.
