If you only experience premature ejaculation occasionally, it may not be serious enough to see your doctor about. But you should also know that premature ejaculation is both common and treatable. Basically, you should see a doctor if your premature ejaculation is causing you emotional distress, relationship problems, or if you and your partner are trying to conceive and premature ejaculation is causing problems with that. If premature ejaculation is affecting your self-confidence, and causing you to avoid sexual activity, you should definitely talk to your doctor.
