About a week ago, I had unprotected sex with a girl I do not know too well. She uses an IUD birth control and is allergic to Latex, so we did not use a condom. About 3-4 days later I started having a slight itch on my penis that i could quite find where it was coming from. Finally, I saw a redness on the left semi-circle of my penis. It is at the bottom of the head of my penis, and then goes around to the underside, and the up towards the tip. Of course it has cause anxiety. But the itch isn t too bad, but to the point where i feel it sometimes. Looking for some Help! Thanks
