Please keep us posted, OP.
I found their website. It looks like there's no spiritual component at all, it's about teaching tantric technique, or "advanced sex", as the leader calls it. If things are getting out of hand, it sounds like the leader doesn't have any teaching or rules or precautions to ensure that things don't get out of control. There are people who give tantric sex workshops in the US, but as far as I can tell, they're well-managed, respectful of personal boundaries, and so on.
