I have tried Viagra Super Force when I was despair to find an effective solution for my problems with erection. Actually I have been suffering for more than three years from these or that sexual performance disorders, but to tell you the truth I do not have too much sex, as I am 50 and my wife is 46. We are getting older and older, we get tired quickly and easily and by night we have no energy for sex. So we have just occasional intercourses, but recently the number started to decline as my penis decided he's not in charge any more. But you know when sexual relations are not frequent the importance of these rare moments is growing and it is really very sad to fail. So after three years of watching my libido to come to nothing I went to a doctor. He told me about Viagra, I read some info on the net and decided that I am too old for half-measures. I ordered Viagra Super Force and now this medication is the best drug I have ever tried. Not only my erection quality increased, but also the frequency of our sex doubled. With the erection I have, being tired is not an argument good enough for continence.
