Cages and cells, anything with metal bars that stop you from getting in a and out. I found out I liked it when I sat inside one of the dog cages we have. I like it so much becuse of how safe it makes me feel. Also a pet kink, as I'm being treated as a pet, put in a cage, wear a leach and getting pats. It makes me feel loved and protected. Also have a thing for masks, specifically gas masks but any mask works. I like that becuse I can't see their faces, I often have a hard time reading people's faces.

The pet thing started early, getting pats on my head by my parants, and then also by classmates. One day I wore a choken with a metal ring on it, and my girlfriend grabbed it as if it was a dog collar.
