Patient: Do men also reach a stage like menopause as in women, secondly, I am 52 years of age, about three months ago, during sex with my wife, I hit my left scrotum to her bottom, an I felt a serious pains. Since that time, I noticed a slower stiffness or reaction of my penis. Could this be psychological problems or not. In the past, when I see a lady or nudity, my body used to move, but now, when I see such lady, I do not react. Please what medicine should I use
