Hi, Thank you for using Health Care Magic. As you know masturbation does not cause acne is right but for you acne always comes with masturbation activities is also right as you are 100 percent sure. Masturbation is normal practice in male specially in young male , while masturbation semen is coming out of penis at final excitement time. This semen is made up of sperm which is secreted by testes as well as fluid which is secreted by other sex organ like seminal vesicle , prostate and bulbourethral gland. This fluid is necessary for keeping sperm motile and viable. This fluid consist of amino acid , fructose, zinc, various enzymes etc. the body always get these material through normal food, and no special diet is needed for maintaining level of these material in body. secondly acne is a skin condition usually in adolescence due to changes in androgen (like testosterone) level. oil containing sebaceous gland are more common on face and upper part of chest so acne usually occurs over there. So acne and masturbatory activity both seen during adolescence time so it is highly likely that one may think that one condition is producing other condition or the opposite. Acne usually subside in most of the person after 25 to 30 years. Masturbatory activity has been associated with lots of myth and i appreciate that you have chosen scientific way to solve your query. Hope , you find this helpful. Regards.
