Premature ejaculation & ED. For 3-4 hr.

If you want longer sex duration, you may try to learn ejaculation control but it may not be a guarantee. When a man has sex, the pleasurable feelings stimulate the brain. if the stimulation reaches a peak, the brains end a signal for ejaculation to happen. So the best way to have more sex time is to learn how to postpone ejaculation. This can be done by many means right from taking mind off sex when ejaculation process stats.. It can be also achieved by wearing a condom or using anesthetic sprays for the penis head. When a man ejaculates, the next erection cannot happen for a period of this is called "refractory period" . This is very essential for the health of the penis. Erections happen due to excess blood flow to the penis. In any organ blood flows and goes back to the heart after circulation, which is in seconds. In penis, the structure is peculiar, the blood which comes, flows into a cavernous structure and this swells like a sponge. The swelling then pushes against the walls of the penis and the veins draining the blood from penis to heart are compressed. As a result for the amount of blood flowing in the penis, the amount returning to the heart is very small. So penis gets erected due to stagnation of blood. Once blood stagnates its oxygen is used up very fast and this deoxygenated blood will harm the penis. hence erections are meant to last for few minutes ONLY. After ejaculation the veins open up and the stagnated blood flows back to the heart. So the refractory period guards against any immediate damage to the oxygen starved penis tissues by allowing a good normal blood flow. A 14 year old can have 5 erections one after the other, because the refractory period is very small. But as age advances this increases, so in 20 year olds it may take about an hour or more to have another erection. So one cant do much about it
