It is natural that young men are interested in sex. It is not at all dangerous neither for you physical and nor for your mental health. There is no reason to be angry att yourself. If men were not interested in sex, there would be no mankind. When you get older, this interest in sex will become less intense. A psychiatrist can give you pills that takes away the desire, but I do not think it is right to give medicine to a healthy young man only because he is normal. I am sure that God will understand you, as he has created you.
