“If a guy simply taps me on the shoulder, I just swoon. Even when I go to the toilet, my body reacts. I’m a little bit scared of myself,” one woman sufferer tells Shukan Post.

Another adds: “When I got on the train one day, I could feel blood gushing toward a certain part of my body and it felt so good I almost let out a moan. It was sheer murder when everybody got pushed into the carriage.”

Yet another woman has her say.

“Even the vibration of my mobile phone is enough to set me off,” she says. “My friend said there’s something called Iku Iku byo (Cum Cum Disease). I guess I’ve got that.”

What may be afflicting these women, the best-selling weekly says, is an ailment called persistent sexual arousal syndrome (PSAS).

PSAS has been described as an affliction that brings about orgasm through the slightest of jolts regardless of whether they’re aroused, or even thinking about sex. What’s more, orgasms experienced by PSAS sufferers are not just momentary phenomena, instead affecting women over anywhere from a few days to a week, with one reported case seeing 300 orgasms in a single day.

Remember that movie idea I had a few years ago: Women in Heat? Hmmm?

OK, I am trying not to laugh, I swear.

But the Japanese to call it Cum Cum Disease!
