The rule’s calculated minimum acceptable partner ages seem to fit men better than women.
Women’s preferred maximum partner age: Examining maximum preferences, again the rule is more lenient, offering an age range with which most people are not comfortable.
Women in their 40s think that approximately 35 or older is acceptable for marriage or a relationship.
Even when fantasizing, such women’s minimum age preference remains over 30.
But fantasies, of course, are not generally subject to public scrutiny and the rule is only designed to calculate what is socially acceptable —so this discrepancy is not necessarily a failure of the rule.
