Hi, im an 18 year old, who has been a virgin up till recently. Today, after being with my girlfriend, (oral sex being the only thing we did today) we noticed my penis looked different. As far as I can tell. There is a bulge right under the head of my penis, and above the scar of my circumcision. It wraps all the way around my penis. We thought it might be because of me recently starting to be sexually active. I waited for myself to become flacid, to see if it went away. Thinking it was a build up of blood or something. Well, its still there. I'm not sure how else I can explain it. I'm really worried about it. (who wouldn't be, not knowing whats going on?) if anyone can help me out, let me know what might be going on, please do. Oh, and it doesn't hurt. It did itch...But that could have been from me being worried.

Thanks for taking your time.
