How often do Americans have sex? The average Americans have sex once a week. A Taiwanese woman I know has sex with her short American hubby everyday. They put a penny in a jar after having sex. After 4 years, 5 jars are overflowing with pennies. Some American guys adamantly remain virgin before they get married. My hubby is from a very conservative family, and his father told him to stay virgin until marry. Of course he didn't listen to his dad.
