>>18311957"Women rapidly lose interest in sex once in a stable relationship or living with a man. Conversely, male sexual desire was found to remain constant, or even increased throughout the course of the relationship.
The more men love their wives, the more they want to have sex with their wives. The more women loved their husbands, the LESS they wanted to have sex with those husbands.
Men showed affection by initiating sex, sharing leisure activities, and doing housework with their wives. By contrast, women showed affection by reducing negative or antagonistic behaviors (e.g, nagging less and being less annoying)."
