Do you wish you had a larger penis? Do you wish you could enjoy intense, lengthy sex sessions with your partner? Well, thanks to Viagra, you can experience much longer and harder erections. When taken in conjunction with sexual stimulation, Viagra enables men to maintain and sustain an erection. Although it will not actually increase the size of your penis permanently, Viagra will enable you to remain hard longer. Therefore, it may seem that your penis is larger. Blood flow is increased to the penile region to make it erect, which results in a temporary increase in size. However, your penis will return to its normal size once the effect of the medication wears off.
