Due to many environmental and biological causes, premature ejaculation is one of the most common complaints men, especially younger men, have about their sexuality. In a recent poll at UCSB, 65% of male students reported experiencing premature ejaculation at least on occasion. It must be stated that premature ejaculation is a very common problem that many men experience.
Premature ejaculation is a very subjective concept, and is heavily defined by a person's outlook. There is no defined length of time after or before which an orgasm is labeled as premature, mature, post mature or what have you. The only premature ejaculation is an ejaculation before it is desired. Sexuality and sexual behavior is very fluid, and can vary a lot depending on your goals. If your goal is to have an enjoyable time by your self or with your partner(s) then the entire sexual experience should be your goal, not just the brief moments of orgasm. By focusing on the whole sexual process, I think you will find that it can be a very gratifying experience with a quick orgasm, a delayed orgasm, or no orgasm at all. They all have their different feelings and can be very enjoyable and gratifying in their own right.
However, since orgasmic control, which increases the enjoyment of sex, is very closely tied to the topic of premature ejaculation, several therapies can be discussed. Several specific sexual positions can be helpful when working with premature ejaculation. The Start-Stop Technique, which is a therapy designed for sex for one, but can be applied to sex in general as well. The Squeze Technique is equally suited for sex and sex for one. In addition to these techniques, learning the truth about certain sexual myths can help ease the anxiety and problem of premature ejaculation.
I hope that the information in the included links is able to help you. If you are still frustrated after trying to follow the advice, and are interested, a sex therapist in your area might be able to give you more personalized information.
