<s>[INST] my penis is itchy and the foreskin looks a bit dry and flaky and tiny white spots appeared just under the head of my penis. It itches only a bit now, used to itch a lot a couple of weeks ago but is better now. Plus there is dirt like i havent washed it in days just over-night. What is it? [/INST] hellothank you for trusting HCMDear many causes for dry flaky itchy skin on penis.most common causes are1. friction:Dry masturbation, prolonged sexual activity, and even constant rubbing against clothing all create heat and friction. These can strip away the body’s natural lubricating oils, leaving the skin feeling dry and parched. Dry skin is also more susceptible to surface-level damage, meaning that even normal activities can cause microscopic tears in the outer layers of the skin; this can result in a penis that is sore and tender to the touch.2.Allergic Reactions — Skin allergies and contact dermatitis (eczema) can cause skin irritation, rash, flaking and dryness that can be difficult to combat. Some common culprits that cause adverse skin reactions may include the chemicals found in laundry detergents, soaps, latex, spermicides, deodorants and fragrances. Plants such as poison ivy, poison oak, and even ordinary grass can also cause allergic reactions in some men.3.Soap or body wash – Even in men who do not have allergies to the chemicals found in some personal care products, regular body bars and shower gels can cause dryness and extreme irritation of the penile skin. These products often contain detergents that are designed to clean away sweat, grease, and dirt, but may also strip the skin of its natural protective oils.4.Yeast Infections — While yeast infections (caused by the Candida albicans fungus) are more common in women, men can also be affected. Individuals who have a depressed immune system due to diabetes or other systemic disorders, who are undergoing chemotherapy, or who are taking certain medications may be more prone, but yeast infections (also known as thrush) can happen to anyone. Aside from dryness and peeling, symptoms can include painful cuts or fissures in the skin’s surface, as well as a thick, pasty or chunky discharge.so please avoid allergen,use moisturizer cream,use candid b gel for local application,if symptoms not improved please consult your dermatologist he/she will examine and treat you accordingly. I think I answered to your question if you have more questions feel free to ask.take care </s>
