You might be so turned on by your partner that you cannot wait to get in bed with her, but sex is over soon, because you cannot resist to ejaculate. If you do not dare to talk with your doctor or friends about it, then read this article for a few tips to better your performance.
In case of premature ejaculation, masturbation is good for you. It is the easiest way to take charge of your sexuality. Start and stop method might be the best to use in this case. Stimulate yourself until you are on the verge of orgasm, then stop and let your body calm down. When you start again, you only need to become extremely horny quickly, but slow down after you reached it, and let yourself slowly come back to the verge of orgasm again.
Foreplay is also a useful tool that you can use. It will make the intercourse last longer without actual penetration. You can give your partner one or more orgasms before you would get to yours after the actual action began.
You have various other tools, as well. A penis ring in the right size can keep the blood in your penis, for instance, but they can close your urethra, so your ejaculation will be held back. Since a condom can also tighten that tube, it can also help with your problem.
Last, but not least, define what exactly premature means to you. Most girls do not expect you to hold on for hours, and in fact, the average length of an intercourse is usually around five to fifteen minutes, so unless you cannot hold on for at least three minutes, there is nothing to worry about.
