Sex drive in men depends on sex hormone, testosterone. If the level of testosterone is lowered, libido (the source of sexual interest and excitement) will be probably lowered, too. The main cause of lower testosterone levels may be physical, such as problems with a liver, kidney or pituitary gland, but also side effects of some medications, as well as fatigue, stress or pain. However, the most common cause is mainly of a psychological nature.
Some men generally lose their desire for sex, although the loss of interest usually occurs in relation to their partner, especially if the relationship between the partner is burdened with some other problems (which may or may not be related to sex life). Due to problems, such as impotence or premature ejaculation, that hinder sexual enjoyment, a man may begin to avoid sexual life. In addition, sometimes the problem that occurs with one partner is repeated with other partners, until sexual life becomes generally unattractive.
The general loss of desire for sex life is not common, but it often occurs in a sexual relationship where there is no more excitement.
What to do?
Use the recommended self-help measures below, and if they do not help you contact your doctor who will probably check if the cause of your condition is some kind of a physical disadvantage. If the examinations shows that you are physically healthy, you will be referred to a specialist for sexual or marital problems.
Self-help: you should talk openly with your partner and thus resolve any misunderstandings. If your sex life has become boring, try refreshing it with new sexual approach.
Professional help: the treatment depends on the root cause, which is often difficult to find. Psychotherapy can help with certain problems, such as impotence or premature ejaculation. Treatment includes self-exercises, conversations about relaxation methods, as well as reviewing some facts and ways of sexual excitement that you may have forgotten.
