This study examined the effect of socioeconomic-cultural homogamy on the marital and sexual satisfaction of Hong Kong Chinese couples. Using a representative, territory-wide sample of 1,083 first-time married heterosexual couples, this study found that wives were generally less satisfied than their husbands with their marital and sexual relationships. Husbands were more likely to be satisfied with their marriages when they were two to four years older than their wives than when they were of similar age to their wives (i.e., within one year of each other), but they were less likely to be satisfied with their marriages when only their wives were employed than when both partners were employed. In addition, they were less likely to be satisfied with both their marital and sexual relationships when their wives were five or more years older. Wives with an older husband were more likely to be sexually satisfied than wives of the same age as their husband, but they were less likely to be satisfied with their marriages when they were better educated than their husbands. The implications of the findings are discussed.
