Male Orgasmic Disorder: Delayed Ejaculation

Persistent or recurrent delay in, or absence of, orgasm following a normal sexual excitement phase during sexual activity that the clinician, taking into account the person’s age, judges to be adequate in focus, intensity, and duration.
The disturbance causes marked distress or interpersonal difficulty.
The orgasmic dysfunction is not better accounted for by another mental disorder (except another sexual dysfunction) and is not due exclusively to the direct physiological effects of a substance (e.g., a drug of abuse, a medication) or a general medical condition.
