45 days ago i had protected sex with an unknown girl. After ejaculating (when I had some sperm on my penis) she gave me blowjob which only took 20-30 seconds. I didn't see any blood in het mouth and there was not any cut or sore on my penis. I have small infection in my left ear and in the same side a small swollen node. I have no opportunity to make test.
What's my risk? I am in risk?
