I'd like to share some links with you guys.

Here's a link to a great documentary about Insex, called Graphic Sexual Horror.
A wonderful 'behind the scenes' of one of the most notorious BDSM websites.

Another really interesting documentary I'd like to share with you is called Sick.
About the life and death of performance artist 'supermasochist' Bob Flanagan.
