I have heard some scientists are working on birth control pills for *men*. And yes, japan is very much like that. It's a good thing, and a healthier society. America is full of whackos - mostly. :\
Know what's funny about the difference in sexuality in japan and america? 'America' has sex four times as much as 'Japan' does. Statistically speaking of course. Even though its forbidden and evil here, that's what makes them do it more. Just goes to show, nudity is nothing bad, nor is sex.
