I've seen this before in The Coven of The Double Flame, a witches coven based in Victoria, Australia. Or at least it was a coven as it's disbanded now. It's leader was a guy who I will not name (as he's out of prison now, and "yes" I knew him) but he also had this Goddess being a "virgin / whore" thing going on. In fact some of these posts here I would swear are so close to his beliefs that I'd bet money it was him on this forum.
The Coven of The Double Flame was disbanded by the aurthorities, the leader jailed for a variety of offences. His followers.....? Some went to join other covens, and (I was told) were so messed up that they needed "de-programming".
I can see how a person can have a Goddess belief that strongly leans towards a Virgin-Whore belief structure. I see nothing wrong with that. I've seen religious practices that even here would be described as really really bizzare and very erotic in their meaning. Dos'nt make them wrong, just individual. But that's the important thing right there - Individual. What's great for one can be not-so great for someone else.
I find this discussion facinating (on both sides) and would like to know more, but perhaps a seperate thread devoted to the subject may be in order. After all, this thread was started by someone who's intent was not to start a fight. And the night sky is a wonderful thing to look up at.
