The Conspiracy against Sexual Energy

This:

The battle will rage most fiercely around the question of sex… Mankind must learn that the sexual instinct is in its true nature ennobling. The shocking evils which we all deplore are principally due to the perversion produced by suppressions. The feeling that it is shameful and the sense of sin cause concealment, which is ignoble, and internal conflict which creates distortion, neurosis, and ends in explosion.

-- Aleister Crowley

I gradually came to work with tantra in self-sex, as part of my meditative process, but it's been a self-taught process. I have a blog post where I talk about what, how, and so on, which a) is too long for ATS and b) I am not about to share publicly on ATS given the topic LOL. However anybody interested in a woman's account of it can read:

Along your lines, any form of contraception or prevention would also be a "waste"...

Perhaps if we had communes for all those un-named children...

Me? From your perspective I would almost appear to be either asexual, a polygamist, or a total puritan.
