Ever, during periods where you have no one to play with, engage in self-masochism just for the "fun" of it? And if so, what do you do?

I'm still new to the masochism thing... I had my mind closed to the idea for a long time before this place pretty much blew the door open. But I'm running a little experiment on myself with a couple clothespins as we speak. It's... interesting, though I don't know if I'd call the sensation sexual on it's own at all. But I'd be lying if I said I wasn't enjoying it.
