I was in several months ago for one of the clinic's paid experiments and ever since then I haven't been able to cum. My man rod will get rock hard and I can do everything else, but I can't seem to reach an climax and cum. It began at very first happening every once in awhile and then increased to every time I stroked off or had sex. Finally, I just got so frustrated with my body, that I called the clinic up and made an meeting to go in and see the doctor. Sure enough the Doc that I was watching was Dr. Phingerphuck the one that I did the experiment with. I explained the situation to him and he seemed to think that it was pretty easy to fix. He took down some general information and then asked me to eliminate my shirt. He listened to my heart and lungs for a minute, and then took my blood pressure. Afterward he said that it was a tiny high, but I told him that I had a cigarette before I came in. Next, the Doc asked me to take off my footwear and trousers in order to take my weight.
