@ Helter Skelter... the ones I personally read are more along the lines of being for submissives, however, if you have a look at DrWakko’s blog, I think he has done one that has a list of books. I think there’s also a forum here that has done the same. The authors who’s books I’ve found quite informative (and who write for both Dom/mes/Tops/subs/bottoms), are Janet W. Hardy and Dossier Easton. However, there are many.
As for podcasts, my favourite is Rainbow Connection, which again, is more geared towards subs... however there are heaps of podcasts to choose from on the main page here.
As for blogs and forums, I try to read most of them. It helps in many ways... not only for learning, but for support.
I think a healthy mixture of both private and community, while not absolutely necessary, is good. I am a member of a few local groups (it’s a small place... pretty much all the same people lol), however I’m not necessarily active in the play aspect. I just find it nice to be able to be around people I can comfortably be myself without having the exhaustion of constantly feeling I need to censor myself. I’m not sure about @ Hawkeye’s experiences, however I know for myself that I haven’t personally experienced any abusers within my local kink community... our group is very focused around SSC, RACK play, education and skillshares. I do, however agree with him when he says, “develop real relationships with like minded people.” To me, that’s what it’s all about. Hope that helps a bit... good luck, I hope you find what you’re looking for
