I am a 21-year-old man. During sex, my girlfriend was giving me a blow job. Suddenly her nail tore into the frenulum of my penis and there was a lot of pain and crazy blood. I’ve been very worried about it. Now there is not so much pain and blood. There is a centimetre tear towards the middle. I read on the internet about it and found that Neosporin helps and I used it as first aid. Now I’m wondering whether I should go to a doctor or will it heal automatically? How much time will it take? I am so tense, please reply soon.
