This technique is very, very simple. To last longer during sex, relax your PC muscle and keep it relaxed. The PC muscle is shown as a thick black curved band in the diagram below:

PC muscle relaxation is a highly effective technique for having sex as long as you both desire, without stopping. The PC muscle is part of the pelvic floor muscle group. The PC is the muscle you squeeze to prevent yourself passing urine. It's close to the perineum and it's also known by the slang names 'gooch' and 'taint'.

'PC' stands for pubococcygeus, from pubic and coccyx (tail bone). As you can see above the muscle connects the pubic bone to the tail bone.

You can feel it by pressing gently into the flesh between your testicles and your anus. If you tense the muscle with your fingers there you can feel it bulging slightly.

This is quite a rare technique as you can read about in the history of PC muscle relaxation.

To make sex last longer, relax your PC muscle. As soon as sex begins, relax this muscle and keep it relaxed throughout. This will help you to stay away from orgasm and avoid premature ejaculation.
However, its natural to tense this muscle during sex because it feels good. If you do tense it, you'll get to orgasm quicker. So, to last longer, relax your PC muscle from the moment of penetration onwards, and keep it relaxed.
You can practice this with your partner although you will learn much quicker on your own first, while masturbating. Learn what it feels like to focus on relaxing the muscle.
 

Why PC muscle relaxaton works

The technique works because the PC muscle sits right beside the prostate (see the diagram above). The prostate plays a central role in orgasm and ejaculation. When the PC muscle is tensed, it puts pressure on the prostate and brings orgasm quicker. Relaxing your PC muscle reduces pressure on the prostate and helps avoid premature ejaculation. It also reduces pressure on the surrounding organs, the seminal vesicles and the ejaculatory duct, both of which play a central role in orgasm and ejaculation.

You can see the direct effect pressure plays in orgasm control yourself. Try masturbating with one hand and use the other to put some pressure on your perineum. Notice the difference? It feels better and you'll come to orgasm quicker. That's because you're physically squeezing your PC muscle with your fingers, and indirectly, your prostate.

Traditionally, sex lasts only a few minutes before the man orgasms. As soon as penetration begins, the man tenses his PC muscle (usually without noticing) because it feels good. Moments later it's all over.

By relaxing your PC muscle, pressure is taken off the prostate, orgasm is delayed, and premature ejaculation is cured. The aim of longer sex is to stay away from orgasm.

This helps to keep sex going for as long as both you and your partner desire, and improves the chances of your partner having an orgasm during sex.

That's not to say you can't orgasm during sex! After having sex for longer you can of course have an orgasm. The longer you leave it, the more satisfying the orgasm will be for you.

The opposite problem: if you go soft

Sometimes if you concentrate too much on staying away from orgasm, you may get the opposite problem: you start to lose your erection.

This is easy enough to fix: tense your PC muscle (the opposite of what you've been told above). This increases pressure on your prostate, increases pleasure. When you feel your erection is back, you can then go back to relaxing your PC muscle. You have to get the balance right between staying hard and staying away from orgasm, but with some practice this becomes very natural.
