Premature ejaculation is where a man ejaculates (comes) too quickly during sexual intercourse. It's a common ejaculation problem. A study involving 500 couples found the average time for ejaculation was about 5-and-a-half minutes after starting sex. This time could be longer for men who have sex with men.
International guidelines define premature ejaculation as regularly ejaculating within 1 minute of entering your partner. However, it's up to you and your partner to decide if you're happy with the time it takes you to ejaculate. If ejaculation times are causing you persistent distress then it's a problem that can be helped with treatment.
There are 2 types of premature ejaculation:
1. primary premature ejaculation - where you have always had the problem.
2. secondary premature ejaculation (or "acquired premature ejaculation") - where you recently developed the problem.
The causes of primary premature ejaculation are often psychological, such as having a traumatic sexual experience at an early age. Secondary premature ejaculation can be caused by both psychological and physical factors. Physical causes can include drinking too much alcohol and inflammation of the prostate gland (prostatitis).
