Male Orgasmic Disorder is the inability for a man to have an orgasm despite lengthy sexual activity. It can be a regular delay in orgasm, or the total absence of an orgasm altogether. The man may have sexual desire in the first instance and be able to achieve sexual arousal, but he cannot orgasm. It can be associated with other disorders, for example Male Erectile Disorder. The reason for Male Orgasmic Disorder can be physical, but the most common cause of the problem is psychological.
Physical problems can include thyroid disorders, diseases that affect the nervous system, surgery and substance abuse. Certain medications can also cause the problem.
The psychological reasons are many and include depression, anxiety, low self-esteem, fear of getting their partner pregnant, fear of contracting a sexually transmitted disease like HIV, being brought up with taboos about sex or a past history of trauma as a child, for example being subject to sexual abuse. All of these reasons are valid and can have a profound effect on a man being unable to achieve orgasm. Environment can also factor. If there is nowhere private the thought of being interrupted may cause anxiety, this can also contribute.
Male Orgasmic Disorder is relatively quite rare.
