I m unmarried. I have noticed for the last one week I m struggling to achieve an erection and also my libido has gone very low and can notice some shrinkage in my penis. I m baffled as to what could be the reason, could it be stress or tension? Because I m jobless and I have lot of tension but apart from that I take care my health by eating the right food, workout 6 days a week. Please advise some permanent treatment because I will have to get married by end of this year.
