instruction: hello doctor I am 21 years old I have been worried because my penis head has turned blackish and I have horizontal wrinkles on it I masturbate once a day for the past three years and often forget to clean the sperm after masturbating please suggest
output: hello I read your query and understand your concerns I have gone through the attached images and it is true that there is some black discoloration at the glans penis head but it does not look like symptom of any illness or disease in other words it can be stated that poor personal hygiene can be the cause and exercising proper care during bath and otherwise can be of much use I must acknowledge that images attached to the query are of low resolution but can be considered of average quality for the initial assessment in case there is no improvement after improving personal hygiene I recommend you to post high resolution images on the follow up query I must also inform you that slight black pigmentation of the penis can be due to the overproduction of melanin which is responsible for the color of our skin this generally represents injury to the penis because of some injury due to aggressive masturbation which may be applicable in your case so it is important to remain gentle with yourself when you hold your penis next time I recommend you to wash with a mild cleanser and rinsing thoroughly so that dead skin can be removed which will change the color to the original it is also recommended to use antioxidants and mineral rich diet in your daily schedule to rejuvenate the skin of the body I hope this helps
