Sexual issues in Japan: truth or not?

[sasha]

Japanese culture makes a clear distinction between a childless woman and a mother. Mothers are not seen by their husbands as sexually desirable anymore. Once a child is born the mother becomes like a relative, not a sexual partner anymore.x

 

so my mate and i've been discussing some issues that are said(by this guy who lives in Japan) to be common there. mainly this^ - once married and with child/children they stop having sex with their spouses, sleep in separate bedrooms and often cheat. i think it's too stereotyped, culturized Madonna–whore complex - sounds stupid, but my mate is all "why not?" so those who are acquainted with japanese culture - what do you know?

Did a non-Japanese say this? Or a real Japanese person?
