Heh, that's lovely! :D I guess when it comes to a compliment, it just doesn't get any better than that! :) Totally deserved, mind you. I know squat about BDSM scene, but you could have totally fooled me you were some kind of an expert, if not an active participant. It's that kind of comments that really give you the boost, isn't it?
I've also had one like that this week: a guy told me that he was re-reading my fics cause he always finds it inspiring and he was making a fan-art video/mix compilation based on one of them. I could totally kiss him, goddammit, why are all the good ones gay!? :)
