Premature ejaculation may occur as a side effect of erectile dysfunction.
However, erectile dysfunction is where a man has problems gaining or maintaining an erection during sexual intercourse. If you do not have those problems, it is highly unlikely that your premature ejaculation is a sign of erectile dysfunction.
Erectile dysfunction and premature ejaculation can often come as a pair whereby one may cause the other. During sexual intercourse, if you find that you often experience a loss of erection, you may try to visualise arousing imagery or focus on your sexual excitement to counteract this effect.
This, in turn, can increase the sexual excitement which has the unfortunate side effect of speeding up the ejaculation process and resulting in ejaculating early.
To avoid this, you may then find yourself focusing on reducing your sexual excitement which will ultimately lead to the loss of your erection during sexual intercourse.
This often results in a choice between two decisions which has no satisfactory answer; do you choose between maintaining your erection during sexual intercourse and ejaculating prematurely, or do you choose to suffer from ejaculating early but maintaining your erection during sexual intercourse.
Anxiety can make both erectile dysfunction and premature ejaculation worse, or even cause one or the other. It is not surprising that by addressing your erectile dysfunction, you may find a reduction in premature ejaculation.
Likewise, by treating your premature ejaculation, you may find that you can maintain an erection for more extended periods of time and consequently you no longer have to suffer from erectile dysfunction.
Should you have either erectile dysfunction or premature ejaculation, it is best to speak with your Doctor to discuss a possible course of action to address the underlying issues causing your problem.
