Sex therapist Dr Brian Zamboni suggests shrugging off an early emission with some extra attention to her arousal (yes, that means staying awake), then getting back in the saddle. Most men last much longer the second time around.

And the more you practise, the longer that f rst time will last. If your doctor signs off on it, you could also try Viagra: a study shows it can help reduce your refractory period for that second go-round. While you’re at it, pay attention to the following golden rules:

Please her first

Then she won’t care so much about your hair trigger. Use your hands, mouth or sex toys to bring her to orgasm before you take your turn, says sex therapist Dr Ian Kerner, author of She Comes First .

Let her climb on

When she’s on top, your penis is less stimulated. And ask her to go slowly. “Long and fast thrusting is hazardous to a man’s endurance,” says sexologist Dr Robert Birch.

Practise solo

When you masturbate, don’t let yourself come quickly – it will train your body to finish fast, says Zamboni. If it usually takes you two minutes, try to stretch it to five, and so on. And pay close attention to your arousal, says Kerner. If you can learn to sense when you’re about to ejaculate, you’ll know when to pull out and take a breather during sex.
