Penis glans skin dry and wrinkled from last 4+ months. I didn't notice it. I had sex in Dec 2018. Apply some lotion on my penis before sex but I washed it immediately with bodywash. After 2-4 days I noticed glans bottom ridge get dark red. As you can see in the pictures. I consulted with dermatologist first, he have me Candid-B for applying on penis. After 20 days got no relief. Then I diagnosied some STI (Chlamydia, HSV, TPHA, VDRL) which are came Negative. Now I am getting treatment from a urologist from last 15 days, he also gave me Candid-B and oral medicine.
Anyone here can suggest what is exactly this. And how can I diagnosis it and treatment.
