摘要：Males among many species, including humans, evaluate cues of sperm competition risk and adjust accordingly their sperm competition tactics. The number of potential sexual rivals can serve as an index of sperm competition risk. Therefore, men may adjust their in-pair copulatory interest in accordance with the presence of sexual rivals. Using self-reports from 45 married men, we test the hypotheses that the time a man’s wife spends with other men—either male friends or male coworkers—will positively predict a man’s copulatory interest in his wife (Hypothesis 1) and his anger (Hypothesis 2), upset (Hypothesis 3), and frustration (Hypothesis 4) in response to his wife’s sexual rejection. The results show that the time wives spend with male friends (but not male coworkers) predicts their husbands’ anger, upset, and frustration in response to sexual rejection, providing support for Hypotheses 2–4. Discussion highlights novel contributions of the current research and provides a potential explanation for the discrepant findings regarding male friends versus male coworkers.
