Erotic Twitter Hashtags

So tell me, which are the best Twitter hashtags to be using for erotica writing?

I've just sent this out on Twitter (@catscarlett1):

Looking for like-minded folk to follow #fetish #BDSM #spanking #erotica #eroticwriting #dominatrix #sub 

Hoping that may net me a bit of interest, as I'm still pretty much a newbie on Twitter.

But I've noticed that most of those hashtag searches bring up professionals dealing in those areas.  What I'd really like to find on Twitter are the grass-roots level readers, the enthusiasts and amateur toe-dippers who might like to chat and maybe later entertain themselves for an hour or two with one of my novels.

All suggestions received gratefully. Thanks!
