I believe Cuadernos de BDSM to be the most interesting magazine about domination eroticism bar none. It is a labor of love, fueled by the passion of a wonderfully enthusiastic group of Spanish people who for once don’t stop at the surface of this sexual subculture, but explore it thoroughly in all its implications. In its seven years of publishing they tackled aspects as diverse as archaeology, physics, medicine, law and much more you probably wouldn’t immediately associate with whips and leather.

Yesterday I received the notification that issue number 20 is online, freely downloadable in all of its 187-pages glory. If you aren’t scared by the Spanish language you want to check out a long article about the history of BDSM and a great feature about differently-abled kinksters – but there is much more to discover in there.
Also, I should probably warn you that the official website for the magazine puzzlingly doesn’t collect all of the available issues, which are however downloadable from here(special issues too!) – including issue #14, featuring a long interview with yours truly.
