9 days ago I had protected sex with some girl and a few days later I started getting slight discomfort AFTER I urinated. It was kind of like a warm feeling in inside the penis, not burning. It seems to be inside in the urethra. It lasts a while after urinating however it isn't all the time just maybe when I haven't had a lot of fluids. I don't feel anything during urination either. What I have noticed is that if I have an erection its really warm inside and maybe the odd itch inside. I get a warm feeling inside when I ejaculate too. Ive started applying hydrocortisone cream on the outside under the foreskin and on the top of the penis (not inside) the past day or so as the foreskin feels a bit sore too. Thinking maybe fungal but its been a good few days now though.
Any ideas to what this could be? I have no real burning, no discharge, no lesions, nothing thats a red flag.
