Im 20 years old and having some problems. A few month ago, i got symptoms all of a sudden. A few months ago i was at a point of getting no erections, I believe that a case of excess stress at school mixed with a case of epididymytis really screwed me over. I went to the family dr. got a checkup, i had fairly high blood pressure, fairly low testosterone, and the epdidymitis. Healthy all around other wise. Not diabetic. I tried waiting it out with no avail, had good days and bad days. Tried a few bp medicines and felt worse. The epididymitis is long gone. I started to see some progress with less stress as well. In addition, pot smoking daily for a few months. I got my blood pressure under control without meds! Stopped smoking pot. Let a few weeks go by. Definitely improvements. So I got to a urologist and endocrinoloist eventually. Urologist says everything is looking good and he thinks it is mental, to just give it some time. I will agree, mental certainly plays a role in this or at least makes it worse. Endocrinologist rechecked my hormones in depth and they are looking normal now as well. Here I am today. I can get an erection with stimulation 95% of the time. (For some reason it is next to impossible to get an erections just thinking erotic thoughts, this bothers me as I don't get erections in day to day life which I used to all the time). Also, I am having trouble maintaining, it feels as though i physically need to be constantly stimulating my penis or thinking the most erotic thoughts or else it just slumps. As opposed to before where it would stay hard relatively easy on its own and slowly deflate. I feel as thought it takes extra effort just to keep it hard. I have noticed that the right side of my penise seems to have an area with no erotic sensation, it is possible i have something goin on with my nerves. I haven't noticed this till recently.
