It's a hot and humid day in much of the East so if you're planning to head off to a dungeon this evening to get bound and gagged, you might want to call ahead and make sure they have air-conditioning. (Of course, a true masochist would probably call ahead to make sure the heat's turned on.) In any event, if the thought of being locked in a tiny cage turns you on, this gallery of men in pain/pleasure is for you. (R.S.)
