Hello , i have white sticky patches on the penis and under the covered skin(itching) maybe it is lichen sclerosus . so may i know how this caused ? does it curable permanently ? what is the home remedy for this ? how to prevent it ? thank you?

Keep the area clean and dry and apply OTC hydrocort ointment for a week or so. If not better pl see a Urologist. Self diagnosis is dangerous and from your description the diagnosis is wrong. Good luck

White sticky patches are more suggestive of a yeast infection than lichen sclerosus which is usually dry and extremely itchy. Yeast infection in the genitals can be passed back & forth between sexual partners. Cortisone cream or ointment can worsen a yeast infection so it behooves you to get examined for a proper diagnosis. See your physician, urologist or dermatologist.
