[|Human|] Ummm... Hi? Lol. My girlfriend and I were fooling around and before she was about to perform oral... She bit me, she did it a few times before, in other instances. Nothing happen then. And never very hard, just playfully. But this time it started to bleed out the tip. There s no external wound. And it stopped after about 15 20 minutes. I think it might be a uti, but not really sure. Can you help?!?
[|AI|]  Hi, The skin in the head of penis is thin and vascular. Also, it is elastic and stretchable making it difficult to see any small wounds. You might have got bitten and this led to bleeding when the penis was erect. After 15 - 20 minutes, the penis became flaccid and the bleeding stopped. The wound is not visible because it is small. Please apply any antiseptic ointment and do not have sex or do masturbation for about 1 week. It is not looking like urinary tract infection because you are giving history of being bitten by your girlfriend before oral sex.
