Erectile dysfunction is a sexual weakness in males. It involves weak erection or dying erection. Males afflicted by erectile dysfunction cannot have a normal sex with the partner. There are many factors behind erectile dysfunction.

Lately it has been observed that excess porn watching also could lead to the erectile dysfunction. It has been mentioned that it lowers the sensitivity of the males and makes it harder to get aroused. Such a male finds it difficult to have the erection needed for a normal sexual act. That perhaps explains the increasing use of Sildenafil Citrate 200 mg for younger males.
