1.) I have night fall problem at least 3 times a month because of tension due to external reasons such as offensive language used by some people. Sometimes when I look at some people who are against me then I have a discomfort feeling in my testicles and I know that this will lead to night fall which happens. I control my diet and I am a vegetarian and a bachelor 28 years old. I am having this problem since 1 year. how can I stop this. 2.) When I walk for exercise the tip of my penis gets scratched because if being rubbed against cloth. This never happened since last5 years of circumcision. However, when I was staying in my dorm the person staying on the next floor used to hit his floor, ie. my ceiling, intentionally which many times caused me night discharge, including loss of mind speech coordination, and also it led to an itching/discomfort feeling at the tip of my penis. After any incident of a hit on my ceiling i had this itching feeling at the tip of my penis, then as i walked to prevent a nightfall which I could predict, my penis rubbed against cloth, it felt like a sexual pleasure for sometime, so I continued to walk but as I felt more pain , like that of a scratch wound, I opened my pants and saw a real scratch. I could not walk for some days and had to lift my pants while walking. THis happened many times and I found that the inner layer of the urinary tract, looking from the penis glans comes out on the tip of the penis when there was an impact on my ceiling and when I walk it starts getting scratched. This has prevented me from jogging or walking for many days. I have changed my room now but I am still not able to walk as the tip of my penis tends to contact with cloth and cause lot of dicomfort. It never happened before the incident of my ceiling being hit. Please tell me how can I prevent this.
