Does anyone here spontaneously orgasm upon entering cold water?

A friend of mine told me that whenever she jumps in a body of very cold water, such as the ocean, she has an orgasm! She’s been wondering if she’s the only one who this happens to. I’m in an all-female musical group with her and she asked the entire group of 14 women during rehearsal. None of us had ever had this happen to us, or heard of it happening to anyone else. We were all pretty jealous, though.

Does this happen to any of you? Does anyone have an explanation for why it might happen? I couldn’t think of anything other than some sort of “crossed wires” in the brain.
