Re: Do these pills keep you hard under all circumstances??
I can speak only of my own personal experience with Viagra. It enables me to achieve an erection just as I did when I was younger. If I am physically or mentally aroused, I have an erection. If not, I do not. If the erection lasts for an hour or more, it is because I am aroused in some way, not just because of the pill. Hope this answers your question.
