I practiced a program of stretching an jelqing for about three months. I started to notice pain in my penis and decreased erectile function a few weeks ago, so I stopped the exercises. Then last week after sex I woke up with an even greater pain in my penis. During the week my penis began to lose it’s flexibility in the flaccid state and it is nearly impossible for me to get an erection. It is like my penis is tight and “locked up”. I went to a urologist and he just said it was because of stress and nerves, but I know this is not true. Please help if you have some advice.
