Sex in a marriage what does it take?

To have a good sex life in a monogamous marriage?

If the wife wants a happy sex life more normal sex flow her only complaint is lack of foreplay, sex, romance or intimacy.

I want to post the topics I've read on glow about some relationships. " man won't have sex for months, men won't have sex for months but watches lots of pornography, man has sex once a day or few times weekly but masturbates watches porn several times. Man compares wife to porn asks her to do things he's seen in the videos and some ask for performance when they have sex." "Men is looking at other women even while with wife and women flirt with him even though she's right there. Women have cat called him, he's checked out women and online facebook etc." "The last glow topic is men looking for sex outside the marriage."

What advice as a married woman do you have for those what keeps marriage healthy and the romance alive what makes a husband decide to stay what makes a husband open up and connect
