Every day there is a new must-try tip that is supposed to send readers’ sex lives off into the stratosphere, but they rarely seem like they would actually work. According to a report from the BBC, however, the latest sex tip actually seems to be based on common sense. A new study has shown that parents who evenly split childcare duties reported having a higher level of satisfaction with their sex lives.

The study examined 487 different families, and also found that in couples where women bore most of the burden of looking after children, both men and women reported being less satisfied. Oddly enough, when men took on the greatest workload, both parties still reported feeling unsatisfied.

According to data presented at a meeting of the American Sociological Association, couples where women were responsible for rule-making, praising, and playing scored the lowest on tests assessing relationship satisfaction and conflict, in addition to perceiving a lower-quality sex life.

According to Dr. Daniel Carlson, an assistant professor of sociology at Georgia State University, “One of the most important findings is that the only childcare arrangement that appears really problematic for the quality of both a couple’s relationship and sex life is when the woman does most or all of the childcare.”

The researchers don’t know exactly what it is about sharing responsibilities that leads to a higher level of satisfaction, but it’s clear that evenly spreading the burden of childcare across both parents leads to happier couples with satisfying and engaging relationships.
