Hi, I do understand your concerns regarding hand practice (masturbation). It is a normal physiological process. Once a person becomes sexually mature, semen production starts which is a continuous process. A person then either has sex, or masturbates and has night falls. Masturbation doesn t lead to any sexual, physical or mental health problems. You can masturbate as much a you want and it doesn t lead to any problem. You should consult a dermatologist for treatment of your pimples. With adequate treatment, i can be taken care of. Hope this information was helpful. Best wishes.
