Here are some online BDSM resources I appreciate:
Fetlife is the best social network for most types of kink. If you are interested in anything kinky and are not a member, you probably should become one. My username on there is CareandControl.
This website is produced by Sir Vice, who is the cogent and deliberate Master of soumise, an equally eloquent and service-oriented slave. A little dry and intellectual, which is fine for my engineering sensibilities, though it may temper the interest of some. Both Vice and soumise are soft-spoken and simple in their presentation; they consider situations holistically and are prone to thorough thought on a subject before they make any statements.
I wish this website was half as good as its material, or a quarter as amazing as its authors. Obsidian and namaste are ministers and therapists that have been in a committed M/s relationship since 2000 (collaring in 2003), raising 8 children, planning like corporations and loving like they just started the infatuation period. Whenever I go to a conference where Obsidian and namaste are speaking, I go to every course they teach. I have even happily cried at moments during their presentation due to their love, joy, candor, power and practicality. Their pre-2012 writings are available in the bottom right corner. They have released newer material under the website powerandsurrender.com, which was defunct when this page was created.
This website provides structure, logic, strategies, and techniques for cultivating a successful M/s relationship. The presentation is (more than) a little tacky, though the psychology is generally sound. Also, it includes a copy of the oft-referenced and hilarious “128 Slave Rules ” as an example for potential M/s protocols; while there are many good ideas in there, many are the author’s specific kinks, and several of the “rules” are patently absurd and short-sighted.
A weekly podcast from a married, playfully reflective DDbg couple. Sometimes they focus on particular activities; they usually focus on relationships and psychology.
A weekly podcast from a married M/s couple in an open polyamory relationship that discusses numerous and various kink topics. Several of the topics discussed are not of interest to me, but the podcast on the whole is very well done – somewhat informative and a great background noise.
A weekly guest-driven podcast for a wide berth of kink play and lifestyle topics. Very playful and conversational, sometimes somewhat juvenile.
