There's a fascinating exchange about this over on /sexover30. A pretty random couple (a military guy and an exotic dancer) hook up, have great sex for several days, hook up again a week later, and experience a full-blown, simultaneous transcendental experience during sex. Both are very experienced, with many previous partners, and neither had ever had anything like this happen before. It wasn't something that they were trying to do, or even something they knew about or thought was possible.

I tried to help them put it in context and shared some links to my own research on the subject and to Dr. Jenny Wade's book Transcendent Sex: When Lovemaking Opens the Veil, which is about people who have had similar unexpected experiences with altered states of consciousness during sex.

If you're interested in tantric sex and how it opens the door for this kind of experience, I think you'll find this account fascinating. Here's the link:
