Well I think it might be a bit too personal for most people, and can also get kinda divisive. I remember the last "sex" topic I read was trolled into oblivion by our awesome Loph abbess Annie.

If we're talking "philosophy of sexuality", like sexual ethics, states of mind and sexuality, etc., it might be an interesting topic, but far too personal for a lot of people for a calm discussion, so I'd steer clear, as I also steer clear of any Donald topics...
If we're talking practice and pillow talk, I think it might be better to find a sexuality-oriented online community, and find or create a psychedelic subforum there... Beside, this area is also kinda controversial, with the whole "statutory rape" thing...
Do you believe in the THIRD SUMMER OF LOVE?
