It’s a problem because when you ejaculate you lose your erection and can’t continue having sex. You and your partner may feel there’s not enough time to enjoy it. The condition can be brief and ordinary in unpracticed men, youths, and men who are too very energized or who have gone without sex for quite a while. Most men last more in the event that they have intercourse again after a short time, yet it can take a man anything from a few minutes to a few hours to get another erection.
