Many of those men who take Viagra earlier fought with dysfunctions of erection by injecting medications directly into the penis. Erection that is obtained while taking Viagra, sometimes is not as intense as those erections that were caused by intra-penis injections. Nevertheless, most of these men still prefer to use Viagra, even if the penis hardens only with 70-80% compared to thorough erections caused by the penis injection. At the same time sexual arousal and body reaction to it with Viagra increase gradually in the natural rhythm of sexual intercourse.

In addition, some women do not really like the rock-hard penises of their partners caused by intra-penis injections. Such rigid, superdense organs are unable to adapt to natural outlines of a woman’s vagina. And if a woman has problems with lubricant production that makes vagina somewhat dry - it often happens in older women after menopause - a too hard penis causes many inconveniences and sometimes painful sensations.

We can not forget about the huge difference between the repeated erections which arise after taking Viagra, and the erection after the injections. Even after ejaculation, men who entered a drug substance into the penis can not completely lose the erection, and for some time their penis is hard enough. Such prolonged erections may contribute towards the repeated orgasm, but they can give a lot of unpleasant feelings because the erection of such a nature may last for hours, far longer a man would desire.

With Viagra most men lose erection shortly after ejaculation. But, as already noted, Viagra helps men to achieve a second erection in a natural way, and repeated erection while taking Viagra is obtained even better than the repeated erection in men who do not take Viagra.
