Problem with skin peeling under foreskin

[dc2018]

Hi, the last few months I've been having an issue with skin peeling on and under the head of my penis beneath my foreskin. It appears as small white pieces/strips that usually peel off/become more extended when drying after a shower. Most of the time, it doesn't cause significant discomfort, but on occasion, it can cause some sharp pain/irritation, especially after masturbation once or twice over the past few months. The areas where the skin peels often look worryingly red, but are rarely sore to the touch and there has been no bleeding. I am not currently sexual active and certainly have not been within any time close to when this issue started so there's zero chance it's STD-related. Some days it appears as if the problem is abating, but other days it looks a lot worse, and I'm concerned of potential discomfort/pain and/or off-putting physical appearance in the future. The problem is only beneath the foreskin and not anywhere else on the penis. I'm an extremely hygienic and healthy individual who watches what I eat and washes and exercises regularly. It might be notable that I do also suffer with psoriasis on my head which, as per doctor's advise, I have to regularly treat with cocois ointment and betnovate scalp application or else I get a thick, itchy build up of scaly patches on top of my head. I'm not sure if this could be related to the penis skin issue, and the penis skin issue is certainly nowhere near as bad as what I get on my head, but I thought it might be worth mentioning, just in case. I'd be most grateful for any advise/potential solutions anyone can offer me because I'd prefer not to have to go to the doctor about this unless absolutely necessary. Thanks.
