When you are having great frequent sex, this will add somewhat to the marriage. But if your sex life sucks, then the sex problems alone will very likely destroy your marriage. Sex is how you measure the health of a marriage. There was a show on tv where they brought in three couples with marital issues infront of a panel of experts in relationships. The first question they asked these couples was specifically aimed at the husband. They always asked him, "How is your sex life". Marital problems will always surface as sexual problems, and sexual problems will always surface as marital problems. It's a chicken or egg thing. But if you have sexual problems, it is almost certain that there is marital problem!
