I've never heard this before. The new girl I've been seeing told me that she orgasms during rigorous exercise. I assumed she was joking, but it turns out there may be something to it.

“I was 30 feet in the air during a rope climb one time, and I
couldn’t take it anymore,” Sharon explained.
Despite her seemingly vulnerable position dangling in the
air, it didn’t feel dangerous to her when she peacefully had
an orgasm six inches from the ceiling of her gym.
“It’s an odd feeling in your body, as opposed to an
all-encompassing kind of feeling,” Sharon added. “You’re
more in control. It feels very muscular. I can feel them
coming on, and if I continue doing reps, I’ll get to the
point of climax. But if I had paused halfway up the rope, for
example, I probably could have let it pass.”
