Do you think it's possible to consciously wet yourself, or has modern culture so ingrained the taboo that your subconscious, or even conscious, mind refuses to let you?
If you mean the game, I don't play it. If you mean a real warhammer... all I have to say is that I remember some tv character saying he got kicked out of an rpg club for using a real warhammer, and trying to remember who it was is driving me crazy.
