Using daily report data from 85 husbands and wives for about 100 days each, this paper explores differences in sexual behaviour between menstrual and non-menstrual days. Intercourse and orgasm are reduced during menstruation, in association with impressively less female desire for intercourse during menstruation. In the highly educated group studied, the women respond to a resultant potential increase in male sexual frustration by providing the husbands an increase in non-coital orgasm on menstrual days.
