Flutterby™! :

A particularly good experience at a Good Vibrations workshop last night, learning how to breathe (amazing how much there is to learn about supposedly reflex actions), was the inspiration to dig up these sites:

http://www.tantra.com/hotlinks.html is a bunch of links to Tantra organizations, including Celebrations of Love, and the Source School of Charles and Caroline Muir.

catherine yronwode talks about one of the Celebrations of Love courses in Venus Takes A Refresher Course off of her Sacred Sex page.

And the teacher last night was affiliated with Margo Anand's SkyDancing tantra school.
