It is the difficulty or inability to exercise voluntary control over ejaculation. Typically, premature ejaculation is associated with sexual intercourse of very short duration, but quantifying a satisfactory duration for sexual intercourse is complex. It is more appropriate to define the problem based on mutual satisfaction in the couple. It is the most common male sexual disorder. It is possible to distinguish between a generalized disorder, where ejaculation is always premature, and a situational disorder that occurs only in certain situations or with a particular partner. The definition for generalized or lifelong PE proposed by the International Society for Sexual Medicine (ISSM) is: “A male sexual dysfunction characterized by ejaculation which always or nearly always occurs prior to or within about one minute of vaginal penetration, and the inability to delay ejaculation on all or nearly all vaginal penetrations, and negative personal consequences, such as distress, bother, frustration and/or the avoidance of sexual intimacy”.
