I’ve been a reader of The Straight Dope for years, used to read it in the Boston Phoenix. Got sent here from a link on a long debate on the American vs. British meanings of “brick house.”
Anyhow, I just wasted a morning reading many of the archived columns and came across this one

I happen to know how to produce that effect in women, and since Mr. Adams seemed curious, thought I would post it here.
From my research the ability depends on PC muscle strength, high free testosterone levels, and the proper serotonin/dopamine balance in the brain. I have anecdotal evidence from other women who have tried my approach and had success, but I’m trying to get a small study going on it, because most people think I’m a complete lunatic (except for scientists, doctors and pharmacists) and it would be nice to have some credibility. I do have potential NIH interest, but it’s been a major pain in the ass finding study participants.
Personally, I think that the ability to have dozens of spontaneous orgasms a day is pretty nifty, but most other women think I’m deranged. My thing is a bit complicated, involving eating lots of chocolate, exercising the PC muscles, no caffeine, and some more stuff–basically I have five steps to produce the effect.
