If PM is correct in the statistics they throw out, 50% of marriage end in divorce, but 80% of marriages fail. This means that even of those that stay married, more then half have failed marriages. 20% of marriages are considered PM's, and thus successful. Considering that 85% of women have issues with desire(according to a recent poll), this means that roughly 15% of women are real HD's. This roughly cooresponds with the number of PM's.
