Hello, first or all, sorry for my bad English.
My name is Sahil and I am only 19 years old and it's been 5-6 months I am having problems with maintaining an erection.
It's all started when I was doing sex chat with my girlfriend on WhatsApp. We are on.a long distance relationship and still virgin. I used to do 30-40 pushups daily. While sexting with my girlfriend, I told her that I will talk to you later. After that, I immediately started doing pushups while erected. After doing 7 -8 pushups, I realized that I did something wrong and stopped immediately. Then I relaxed for 5 minutes then tried to get an erection. At that time I successfully got an erection, but it died within seconds. From that day I am having problems to maintain a erection. Also I get erection easily when sitting, and erection dies immediately when I stand up. Also I can get an erection easily when lying down with my knees bent. I feel no pain when masturbating. Before this, I used to watch porn twice or thrice a week. Also I was active 4-5 days with running on a treadmill for 20-25 minutes. I don't smoke cigarettes, no alcohol and no tobacco. What to do now. Please help me.
