Is it normal to want to do "weird things" to my body?
I have this urge every so often to do what I call "weird things." The urge is so strong that it overrides my self-control, and I see more of an incentive in indulging than in not. It usually starts innocently, like in the middle of the night wanting to put on a bunch of makeup (I don't wear makeup) or like today when I got the urge to put an earring on my lip as if I had a piercing. Then it grows - I notice I could also stick stuff up my nose, tie stuff around my head, use beads to tie my face up, use belts and clasps as collars to tie myself to a post, when I used to get dirty to stick stuff up both orifices - I used to buy golf balls just to make a "skewer" with them using a shoelace to then introduce into my butthole. It's almost as if I enjoy BDSM as a self-erotic activity.
I wish this urge would go away, but it just feels so good, and it feels wrong, but I'm not really sure why except that I'm refusing the opportunity to restrain myself. It's annoying because it pops up right when I'm trying to study, and then I get sidetracked.
Is this urge normal, and if so, how do you restrain it?
