"When the instructor gives the command, we’re to breathe 30 quick breaths in unison — it’s an individual exercise, yet we’re working as a group to achieve "orgasm." Heavy breathing, chests heaving, students moaning. Even the normally taciturn ones are sighing audibly. A tingling sensation starts in my lower belly and seems to travel up into my head (like, the head head, where my brain is). The music becomes a loud and powerful tribal chant. People begin to curl over into the fetal position. Climax is achieved!"
