The « Squeeze » method

The squeeze method is simply a variation of the Masters and Johnson method,
except that your partner presses the end of your penis or at its base (crown of
the penis), just before the point of no return and thus stops the orgasm.
Pressure on the end of your penis forces the blood to retreat from your penis
and reduces your erection.

You can use the “Squeeze” method if the Masters and Johnson does not work for you on its own. You can combine both methods.So, you have learned a little more about how to overcome your premature ejaculation problem.

These two methods are an integral part of the Condensed Method. For some
they are successful after a very long work, however, for a large percentage of
people these two methods are not sufficient.

This means that, to overcome your problem of premature ejaculation, you need
other techniques which will enable you to make more rapid progress, on both
the psychological and the physiological level.

Those who have benefited from the Condensed Method discover and try out
several training techniques which teach them to know their own bodies.
And that is the key to learning, successfully, how to stop the ejaculation reflex,
without disturbing your partner’s increasing pleasure.
Let us not forget that ejaculation is a reflex and it cannot be stopped. Yes,
nobody can stop ejaculation once it has started! Nonetheless, knowing the physiology of your own body will enable you to recognise the start of this reflex, without diminishing your pleasure in making love, on the contrary. You will find several ways in the “Condensed Method”.
To overcome your premature ejaculation problem once and for all.
You will also learn how to make love to your partner in a different way, you
will make love together.
In other words, you will be at one with your partner.

For detailed information on the start-stop method and other exercises to delay ejaculation, I highly recommend you to read the ejaculation trainer. If you don't want to read that much or you need immediate results, you need an effective premature ejaculation medication.
