Tracy and Charles, a Young Married Couple, Come to You

Tracy and Charles, a young married couple, come to you, a sex therapist, with this problem: Charles wants to have sex "too often," and Tracy just "can't keep up." Charles blames Tracy for being "frigid," and she blames him for being a "sex addict." What's the solution?

A) There is no simple solution. You have to find out what's going on in their relationship to start seeing possible causes of their disagreement.
B) It's normal for men to have a higher sex drive than women do. Charles can masturbate on those days when Tracy doesn't want to have sex.
C) Men and women's sex drives are similar, but women are socialized to express it less. Tracy can experiment with masturbation more to increase her sex drive.
D) Low sex drive in women is usually hormone based. Tracy can start taking testosterone pills to boost her sexual desire.
