Hi, I'm 22 years old and I do not have firm erections for penetration to occur. That already makes about 14 months. I had varicocele and prior to surgery, I was with this problem. This year I went through a varicocele surgery and during the first month after surgery, my erections were firm, it was perfect. But after the first month, I went back to get progressively worse. What can it be? It is curable? What exams are necessary?
