Sometiems after I wipe myself, i have the urge of smelling the soiled toilet paper. I do not get a kick out of it. It does not revulse me either. It's just an urge that is satisfying, i would find other people's waste absolutely disgusting though. Anybody else?

Though, we don't really need to get so close to our poop.. Smelling it while you're going is well enough to register what's necessary. Unless this is a new habit and in that case your brain may be registering something unfamiliar. Or you lack a decent sense of smell. Or something like that.
