Women in relationships rate male attractiveness the same as women not in relationships. But the latter look longer. Whereas men in and out of relationships look the same amount.
A study by Indiana University neuroscientist Heather Rupp found that a woman's partner status influenced her interest in the opposite sex. In the study, women both with and without sexual partners showed little difference in their subjective ratings of photos of men when considering such measures as masculinity and attractiveness. However, the women who did not have sexual partners spent more time evaluating photos of men, demonstrating a greater interest in the photos. No such difference was found between men who had sexual partners and those who did not. "These findings may reflect sex differences in reproductive strategies that may act early in the cognitive processing of potential partners and contribute to sex differences in sexual attraction and behavior," said Rupp, assistant scientist at The Kinsey Institute for Research in Sex, Gender and Reproduction. The study was published in the March issue of Human Nature.
What I'd like to see as a follow-up study: Measure time married women spend looking at photos of men and then follow them for several years to see if the divorce rate is higher for women who look longer.
Similarly, is marital infidelity higher in women who look longer? Also, is testosterone higher in women in relationships who look longer?
Also, about the men: have any longitudinal studies been done on male testosterone levels and relationships? Married men have lower testosterone. Do men who become more dissatisfied with their marriages experience testosterone increases in a run-up to a divorce?
