Initially, it was considered that the optimum duration for sexual intercourse is about 30 minutes. However, this is proving to be a myth which led to dissatisfaction and more demand from the partner. In a path breaking psychological study done in England, Canada and the USA, it has been proved that the satisfactory duration for sexual intercourse is just 3 to 13 minutes. The duration of 3 to 13 minutes is the duration when man penetrates vagina and to the ejaculation. Yes, one may safely say that the duration for optimum sex is certainly longer. However, it depends on the couple how much time they are willing to devote on foreplay.
The same study has also suggested that the foreplay should be optimum and must be sufficient to aroused the sexual desire of the woman to the culmination point. If foreplay is done perfectly and with due diligence then the chances of woman getting orgasm is also increased. As we all know, about 75 % of woman fake orgasm. Even though, they are not satisfied sexually, they show that they are. The reason is varied and this review is not the perfect place to go for that. For current discussion, it is suffice to say that if foreplay is done with dexterity then the optimum time for sexual intercourse is equal to or less than 13 minutes.
If one consider that there should be more time for sexual intercourse then there is chance of getting disappointment and dissatisfaction. Remember, much part of sexual satisfaction is a mind game. The old adage perfectly set here, 'If you think you can, you can'.
Hence, enjoy your sexual life without thinking about the time. I think every one is capable of controlling his ejaculation till at least 3 minutes. Just try to get yourself ready for some different sexual positions and have healthy and sufficient foreplay to let your lady reach her orgasm.
