Premature ejaculation occurs when orgasm is difficult to control and occurs too quickly. Premature ejaculation is the most common s*xual problem in men. Many people ejaculate prematurely, or "come too soon," at some point in their lives. There is no set time limit for ejaculation. Generally, ejaculation occurs within one minute of penile penetration. It can also occur during foreplay or during penile insertion during intercourse. Some people suffer from premature ejaculation their entire lives, while others develop it. Premature ejaculation can occur at any age, but it is more common in younger men. Ejaculation tends to take longer with age.
