Men don't like to talk about it; neither do their partners. But loss of libido in men or inhibited sexual desire stresses a marriage more than any other sexual dysfunction, according to Barry McCarthy, co-author of Rekindling Desire: A Step by Step Program to Help Low-Sex and No-Sex Marriages.
Losing interest in sex may not be as common an occurrence for men as it is for women: It affects about 15% to 16% of men, and at least double that many women. "But when men lose interest in sex it scares them more than women -- their masculinity is so linked to their sexuality that it is very threatening," says Esther Perel, a couples therapist in New York city and author of Mating in Captivity.
Loss of libido also makes men more unhappy about the rest of their lives than it does women. Only 23% of men with loss of libido say they still feel very happy about life in general vs. 46% of women, says Edward Laumann, professor of sociology at the University of Chicago co-author of The Social Organization of Sexuality: Sexual Practices in the United States. "It bothers men more."
