The sexual desire disorder affects the interest of sex, because the affected person does not respond to the desire for sexual activity in the couple nor has intention to initiate sex. It is a common disorder that occurs when one of the partners does not feel intimate or close to another. The most common causes are problems of communication or affection, lack of time or other relational conflicts. Other psychological disorders such as depression and stress related disorders or infantile sexuality can cause the appearance of these disorders. Treatment is complicated, more difficult in men, so it is required to attend a sex therapy specialist or partner.
