Hi, I read your query and can understand what you are going through. You seem to be suffering from a forms of anxiety disorder predominated by performance anxiety. Further information will be needed to call it social phobia. First of all, lets clear some misconceptions. Since you have mentioned about masturbation, I assume you have some apprehension that your condition might be because of that. Let me assure you, masturbation is a normal physiological process and doesn t lead to any kind of physical or psychological problem. Coming to your current problem, I suggest you should consult a psychiatrist. You will respond to medications like paroxetine or sertraline. Relaxation exercises will help you relax too. Hope this information was helpful. Best wishes.
