I'm a little surprised that, given all the different and horrible means that have been used to torture people over the span of history, that the use of animals to attack/remove the male genitals have not been used. I would think that such a method would strike terror into the victim, and would obviously be very painful. Yet I have heard/read almost nothing about such methods being used, aside from some small references to a woman who employed such methods during the Vietnam War.
There are only a handful of fictional stories out there that relate to this subject, and very few drawings either. I'm not surprised there are no pictures, as that would be a little too much.
The idea of teeth inside a vagina does very little for me. Perhaps because I am the proud owner of one (without teeth of course).
