Viagra vs Injections

Before Viagra became available in 1998 on the pharmaceutical market in the US, a lot of men suffering from erectile dysfunction resorted to the different  injections directly into the penis. Erection that is caused by Viagra sometimes is not expressed how those erections caused by intra penile  injections.  Nevertheless the most of the men prefer to use Viagra, however penis became hard only at 70-80% as compared with 100% erection caused by penile shots.

The main advantage of Viagra consists the it works naturally, the sexual excitement and erection occurs gradually and naturally. Beside, a lot of women do not like when the penises of the their men are too hard. These stiff and too firm genitals are not able to adjust to the natural shape of female vagina. Also some women may experience  problems with the production of lubricant in their vagina. This is very common for women in menopause. In this cases too firm penis usually makes a lot of trouble during the sexual intercourse.

In addition, there is a significant difference between repeated erection caused by Viagra and injection. Even after ejaculation some men that injected a medication into the penis experience an erection. Their penis is still hard for some time. These prolonged erections may contribute to the achievement of the repeated orgasms but often they may cause a lot of problems 'cause the erection may last for some hours.

The most of the patients which take Viagra loose their erection after ejaculation. Viagra helps men to achieve repeated erection naturally. And repeated erections are even better that in men which do not use Viagra.
