I am an uncircumsized male in my mid twenties. For the past 3 months I have noticed a redness and off and on soreness on my penis right above the foreskin and right below the head. It's only on the left side of the penis and there are no other symptoms. No burning, discharge, or open sores of any kind. I went to the doctor and she said it didn't look like an std, and prescriped hydrocortisone cream for the irritation. The cream has not helped and I am wondering if this is psoriasis, balantitis, or something of that nature? The soreness seems to be more intense after masturbation so I was thinking it might be due to friction but after refraining for a week or so, the redness still has not subsided. Any answers would be greatly appreciated.
