#1 Alt.com - The World's Largest BDSM & Alternative Lifestyle Personals. A Supportive Alternative Lifestyle Community! Anonymous Email, Chat, & Instant Messaging! Millions of Profiles With Sexy Photos!
#2 AdultFriendFinder.com - ALT.com and Adult Friend Finder share the same database of members, so
you'll see the same folks (for the most part) on each site. The
differences however, are considerable, when looking at BDSM
relationships and merely adult, casual ones: ALT offers a huge number of
questions to determine your specific kink, and each one is easily
searched by its paying members. For those not willing to pay the
(somewhat steep) fees, try hanging out in the groups or chat rooms to
see if someone nearby shares your interests
#3 Bondage.com - Bondage is a simple name for a great site that is really a true community for BDSM lovers. If there would be more sites like this one we could see the face of Internet porn changed forever. I don’t know if such a trend would ever really catch on, but it’s just great to see some pornographic content rounded out with more interesting and diverse material than simply dirty pictures and filthy films. It’s more than merely sitting back and pleasuring yourself. It’s participating in a growing movement of people choosing to find enjoyment in alternative ways.
