I am a 25yo uncircumcised male who has recently started having sex again after a few months of involuntary abstinance. I now have what can only be described as a friction burn on the left hand side of my penis and foreskin. Is this normal? I thought maybe I'm allergic to the condoms I used but I have used that brand before with no problems. What could have caused it and what do you suggest I do to cure it?

Thanks in advance.
