没去过天上人间。 在美国一年内有多个的女性也只有11%:
The most comprehensive report that I know of on this topic is a US
government survey/study known as "A Statistical Portrait of Fathers and Mothers in America".
The study reports that 11% of adult women in the US -- parents as well
as non-partent -- reported having 2 or more sexual partners in the
past year, and that this percentage has not changed very much in
recent decades.
