... on the giving side, that is, yoni massage. I'm not formally trained but have picked up a lot from videos and writings on the subject. I find it a very enjoyable experience, and the women I've massaged in that way seemed to appreciate my ameteurish efforts.  

I've always wanted to be on the receiving end of tantric massage but haven't tried it yet. I'm aware of some local providers who practice it, eg try searching a well-known web site (which is unmentionable here) that has ads for massage for "tantrictouch".  

There's quite a bit of info online on tantric massage; if you search on those two words you'll find sone good write-ups and videos.  

Years ago there was a lady in NE, can't recall her name, who gave an awesome tantric massage but she moved out of state.
Too hard to describe. Best to research as Knots mentioned.
