ERECTILE DYSFUNCTION is the impairment of the erectile reflex. The man is unable to have or maintain an erection. Like other dysfunctions, erectile dysfunction can be either life long or acquired, situational or generalized. Life long erectile dysfunction is when a man has never had an erection. Acquired is when a man has in the past had an erection but no longer is able to have or maintain an erection either in certain situations or at all. As a situational dysfunction, erectile dysfunction is very common, almost universal. At some time in a man's life he will be unable to have an erection even though he is being sufficiently stimulated. In its situational form, there is a variety of ways it occurs. For some men they are unable to have an erection during foreplay, while others have difficulty only attempting intercourse. Still other men only have difficulty with specific partners but no dysfunction with other partners. Viagra™ is the leading medication for this type of sexual dysfunction.

MALE ORGASMIC DISORDER is an involuntary inhibition of the male orgasmic reflex. As with the other dysfunctions, the man can experience either life long or acquired, situational or generalized Male Orgasmic Disorder. What constitutes a life long dysfunction is controversial. It usually constitutes never having been able to ejaculate in the vagina or a life long ejaculatory inhibition refers to men who have never been able to experience intravaginal ejaculation.

PREMATURE EJACULATION is the third type of male sexual dysfunction. Exactly what constitutes premature ejaculation is unclear, usually a man is considered to ejaculate prematurely if his partner wasn't orgasmic in at least 50 percent of their coital episodes or ejaculation occurred if the male did not have voluntary control over when he ejaculated.
