Premature ejaculation is a male sexual dysfunction characterized by ejaculation which always or nearly always occurs before or within about one minute of vaginal penetration; and, inability to delay ejaculation on all or nearly all vaginal penetrations; and, negative personal consequences, such as distress, bother.
There is no difference between nations and races, and no difference between circumcised and those men with foreskins. Most men will last longer if they have sex again a little while later, but it can take a man anything from several minutes to several hours to get another erection. In books and movies, the male heroes have sex for hours on end, but in real life, such men are the minority.
Make an appointment if PE is bothering you or your partner. The doctor probably will ask if you’ve always had the problem or if it’s a new thing. He may ask about your sex life or your relationships. You’ll probably get a physical exam and remedies or help.
It’s not really known. But your brain chemistry could be at least partly to blame. Men who have low levels of the chemical serotonin in their brains tend to take a shorter time to ejaculate.
Emotional factors can play a role:
Sometimes PE can be a problem for men with erectile dysfunction (ED). That’s when the penis does not remain firm enough for sex. Men who are worried they could lose their erection may develop a pattern of rushing to ejaculate. It can be a hard habit to break.
Treating erectile dysfunction may make premature ejaculation go away. There are many options including drugs like sildenafil citrate (Viagra), tadalafil (Cialis) or vardenafil HCI (Levitra). All of these help men maintain an erection.
