That bf was a fuckin' moron! Obviously, he didn't want you to one-up him in the pleasure scale. Although, it's not an "official" fact, a woman who can do that has mighty muscles indeed!
Damn, what a fuckin' moron. He never knew what he coulda had.
I was with a girl once that had shockwaves (and I do mean shockwaves) whenever she climaxed. She never did what you can/could Star, but she would fart 10 or 15 times before she calmed down. No smells, just rapid pucker action.
