Research has shown that couples who share housework equally have more sex. This is likely because when both partners feel like they are contributing equally to the household, they feel more satisfied with the relationship and are more likely to be affectionate with each other. In addition, when one partner is not constantly feeling overburdened with housework, they are more likely to have the energy and desire for sex.

In fact, one study found that couples who shared housework equally had sex on average four times more per month than couples who did not share housework equally. This study also found that couples who shared housework equally were more likely to be satisfied with their sex lives.

So if you want to improve your sex life, start by splitting the housework with your partner. It may sound like a small thing, but it can have a big impact.
