It is a common belief that the surest way to end your sex life is to get married. But the reality is far more complicated. While it’s true that for many couples, sexual excitement fades in marriage, on average, statistics tracking the sex lives of men and women show that married couples are having more sex than anybody else. Now, if you’re like most married people, you find this statistic hard to believe. But for years, study after study has shown that frequency of sex is actually highest among married couples compared to the never married, divorced, or widowed or even compared to unmarried couples who are living together.
