Delaye ejaculation, also known as retarded ejaculation and ejaculation incompetence, is the inability to ejaculate or persistent difficulty in achieving orgasm despite the presence of normal sexual desire and sexual stimulation. Normally a man achieves orgasm within 2-4 minutes of active thrusting during sexual intercourse, whereas a man with delayed ejaculation either does not orgasm at all or orgasms after prolonged intercourse which might last 30-45 minutes or more. In most cases delayed ejaculation presents the condition in which the man can climax and ejaculate only during masturbation, but not during sexual intercourse.
