Hi, I am 39 years old. My height is 5'7 & weight is 67 & don't have any major health issue. I am not diabetic. My
B12 &
Vitamin D level are normal. Be BP is 122/75. But still since last 3 years I am not able to sustain erection for long time. Also erections are sometime very strong or sometimes very weak. I get morning erections but they have reduced as I used to get 5 years ago. What could be the reason for such issue? Are oil such as Japan oil safe to use? Which oil can give me good erections? Can any exercise help? Can any vitamin supplement help to get strong erections? Can you suggest any safe medicine to get strong erections & sustain them?
