Been having a problem for the past 4-5 days that has really got me worried. Me and my girl (both disease free as far as i know)have sex one morning. Immediately afterwards I noticed the head of my penis had red areas that were slightly risen above normal. I had seen smaller portions of this after sex before that I always attributed to chaffing from, and it always went away in a few days. This time it was worse. The next day I noticed the underside of my foreskin was red and irritated in a ring all the way around. It has been hurting me to pull the skin back to pee ever since. In the following days my penis has been peeling. The red spots on the head are mostly gone, but the redness/irritation on the foreskin has remained. I haven't been able to have sex because it hurts too much.

I would really appreciate some insight here
