I used to be intimidated by people who wrote about sex, even long after I started writing about it myself. The irony, of course, is that people now think the same thing about me. That because I write about sex, I must be particularly sexual. To which my internal response is: "No. You don't get me at all."
A tangasm is not a climax in the way we think of an "orgasm." There is no particular moment of release. The tangasm is not about how it looks, it's about how it feels. A tangasm is a moment of total connection coupled with full-body pleasure, bodies swirling with each other, breathing together, a union with the moment, your partner, the music, the room.
