Could this be the magic pill to stimulate gender equality? New research shows that couples who share equal responsibility in taking care of their children have better sex lives.

Reports Brigid Schulte of Washington Post about this latest finding:

Egalitarian couples who share between 40 to 60 percent of child care duties, from reading bedtime stories and diaper changing to arranging carpools and playing in the park, not only have higher quality relationships than more traditional couples where women do the bulk of the care work, they also have the best sex lives, the research shows.
