Are Japanese youths uninterested in sex?

Instapundit links to this article that cites a survey that supposedly shows that "A startling number of Japanese youths have turned their backs on sex and relationships."

CNN spoke to a Midori Saida, a 24-year-old Japanese woman who described "herbivore men" as "flaky and weak."

"We like manly men," she said. "We are not interested in those boys — at all."

BBC News spoke to one such "herbivore" man (see video above). The man, Yusaki Yakahashi said: "Building a relationship seems like too much effort. To get her to like me and for me to like her... I'd have to give up everything I do at the weekend for her. I don't want to do that."

Are we really talking about sex or relationships? I think it is quite common for individuals to feel sexual and to want sex but to opt out of relationships. They've just lost hope that relationships are worth all the effort and the negatives. I think the distinction is terribly important.
