Degree understand your concerns went through your details. Masturbation is a natural process and is considered healthy if done within moderation. Black spots are not due to masturbation. Size or penis cannot decrease due to masturbation practice. Due to masturbation practice semen cannot be diluted. There are many other factors determining the thickness of semen. Your 5\" erect penis not at all small because even a 2-inch penis can satisfy any woman. STD cannot occur due to the above said problems. I suggest you to consult a psychologist / sexologist in order to gain the required amount of knowledge to clear your anxiety and doubts.
