This Merry Jane article by Sophie Saint Thomas discusses the phenomena of hands-free high orgasm. Find an excerpt below, then the full piece here:

“I came my face off in a tent at a music festival. I had to zip myself inside because I was so high after eating a weed brownie (that I purchased from a hippie couple) that I began having spontaneous orgasms and did not want to be in public. What happened to me? In retrospect, I now know that was my Eve moment: I ate the forbidden fruit and was rewarded with unknown and unexpected sexual pleasures. But surely that was a one-time thing, right?”
