Hi just wondering if anyone could help, I had unprotected sex with a girl on Saturday and the day after my penis was itchy and also the day after that, the next day it wasn't so itchy and I looked in my boxers and there was wet blotches so got in the shower and noticed my foreskin and swelled up and gone really red and there was a couple of red blotches on the head of my penis. Any idea what this could be as I am a little bit worried about it. Thanks
