Last night on UK television aired a documentary called Secrets of the Living Dolls, about men who dress up in rubber suits and masks, giving them the appearance of walking sex dolls. "Maskers" mask for a variety of reasons that were mentioned but not exactly explored on this freak-show doc: to be the women that they can't get, to get attention, perhaps sexual reasons. None in the documentary owned up to this last reason, but one of the members of the family that makes of FemSkin body suits, which seems to be the sole supplier of rubber body suits to these guys, told a group of maskers at a convention, "I don't know what you guys shove up those vaginas, but they can't take it, I'm tellin' ya."
Whatever they do, I'm sure it's interesting. Highlight reel is above.
