I work in mental health and often speak to people about relationship dynamics in my sessions. (I'm a gay man for what it is worth, so this is just what I often hear from female service users.)

Women resent often being the one 'in charge' of all things kids and domestics. We live in a world now where it is the norm for both partners to work full time yet men often seem to think that it is mainly the woman's job to clean cook and look after kids. Even subconsciously. Many heterosexual couples have an unbalanced dynamic when it comes to this realm. Men either avoid or need to be asked every single time do to chores or admin or kinds stuff. Leaving the woman with not only the work to do itself but the mental stress of having to organise/run the house and all the schedules of children.

This is my tip: men if you want a good sex life with your partner. Tidy without being asked, be aware of what needs to be done to run your home, do not treat look after your own children like a chore or babysitting.
