I'm 17 years old. My girlfriend and I were getting into it and slowly but surly she was confident enough to reach down and give me a ha****b. She's a virgin and had never even seen a penis in person before so I let her do her thing, even when it hurt a little bit, to keep her happy and make her feel that she's doing great. Unfortunately this sparked a painful feeling on the upper left part of my penis and directly under the head of my penis (under the left side of the head to be exact.) it's clearly a red friction blister. We talked about it and she apologized over and over. I know for a fact it isn't herpes, I'm the only person she's ever been sexually active with. I'm looking for something that will heal this effectively. Many people say that I'm stuck with this forever and "good luck." I've applied Neosporin on the blister after a hot bath. I also disinfected the would prior to the bath by pouring peroxide on it. I want to make sure this doesn't become infected and heals properly.
