Having problem with my penis, itchy, dry skin.

Patient: My penile head skin has become dry from last three four days and a little discolored as well. though i am not having any pain or itch while urinating but i don’t know something seems to be not normal with my penis from last four five days, i am afraid am i at risk of a STD or something. please help me?

Symptoms: Dryness, sometimes itching, pale yellow patch, discoloration

Doctor: Hello, thanks for your health query on ATD.These type of rashes with dryness & patch may be caused by intense fricti on during sex. My advice is to observe this & use Petroleum jelly twice a day. I think it will clear with no residue.Good luck.
