Hi, I dont know what is the problem. Because it was hard for me to breathe. It was happen the day after masturbating when I go to sleep I was awake and hard to breathe. Then when I try to masturbate again my heart beats fast and there was painful in my chest. And from now I feel the same and I stop masturbating. And when I get nervous my hands was a little bit shaking. Will you help me to find what was the problem and can you give me some advice. I wish you can help me because I dont know what is the problem. Please response.
