qqp question1: Is it okay to have a mild shoulder pain after rock climbing for the first time(on silos)? I don't work out or do much physical work normally. question2: I had a bad habit of masturbation. Sometimes I would do it 2-3 times a day. I used to do it vigorously. This went on for few years. Now my right arm feels weaker than my left. My right shoulder mass and size has decreased drastically. Any advice or suggestions?
