Hi Robin, I read your query and can understand the concern and hesitation you might be having because of your problem. You seems to be having nightfalls, also termed as wet dreams. Once a person becomes sexually mature, semen production starts which is a continuous process. A person then either has sex, masturbates or has nightfalls. It is a normal physiological process. It doesn t cause any form of physiologial or psychological harm. You might consult a psychiatrist who will help you understand the normal sexual functioning of human beings. Hope this information was helpful. Best wishes.
