There is a dude named Master Len who did a whole series of videos about "how to" do all aspects of BDSM. He also has some very entertaining and some extreme videos that are very conversational and informative in their format. www.masterlen.net He is very good at mind and physical stuff.
well...there are no good bdsm movies that i was in...and i was in 3 of them back about 10 yrs ago...though i did enjoy making one of them...but it had nothing to do with what was going on in the movie lol
