I would like to think it is because western white women are not repressed.
You can say women here are less repressed because they have
the right to walk topless in public which is denied to women in
Asia. OTOH Asian women generally feel less pressured to loss their
virginity in their teen years in school. Depending on what your meaning
of freedom is you can either say they are more repressed or they are
not as willing to be exploited by men. Personally I think the biggest
beneficiary of women's liberation in the western world is men. There
was no way ordinary men could have as many pussies one century
ago as we do today.
