Timing can be everything in the bedroom. If you’re climaxing sooner than you and your partner would like, sex may not be satisfying for either of you. It’s a problem called premature ejaculation (PE). It can be frustrating and even embarrassing. It can hurt your relationship too. You don’t have to live with it. There are things you can do to last longer in bed. There is no set time when a man should ejaculate during sex. But it’s probably too soon if you have an orgasm before intercourse or less than a minute after you start. 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.
