Sex in the land of the rising sun

Those hard-hitting journalists at Cleo are at it again with this month' edition containing a controversial little piece about Japanese sexuality.
I hope this starts an international comparison series, but more on that later...
According to these ornery newshounds, Durex has just (in 2001) completed a national survey on sexuality and come up with the following;
* More than 20% of couples don't have sex
* Agencies offer sex 'volunteers' to deflower frustrated 30 yr old female virgo intacto
* A statistically significant amount of Japanese men (?!) will only have sex with prostitutes, preferring to keep their wives as mother figures solely responsible for raising a family.
* There are vending machines available containing the used underwear of teenaged girls.
* A strange fashion trend occurred in which females deliberately hitched their skirts into their panties as an attempt to turn men on and signal tha they were 'available'.
* Japan came 58th in a list of 58 sexually active coutries with the greatest significance given to sexual frequency. Twice a year was the most common amount of sexual activity.

Oookaaay...

Put all this alongside population control measures and we have a confusing situation. Methinks Cleo will publish anything at all with the word 'sex' in it ('cos after all, that's the most important thing for 15-25 year old females to know), and that they're somewhat desperate for material (rehashing a 5 year old study). I guess it's finally hitting them,-there's only so much you can say about sex before you run out of scintillating material. And before you strangle me for buying such tripe, -I read it at work during a boredom session and put it back on the shelf.

So, I wanna know, is the vending machine thing true...?..anyone who has been in Japan recently can answer this one:-)...cos that's just nasty in soooooo man ways.
