This is more detailed version of my previous question so my risk can be assess more accurately. Yesterday I had sex with a random girl whom I met at a bar. I did use a condom and I fingered this girl as well. But earlier in the day I had trimmed by finger nails very short, to the point that one of my fingernails was aching. After I have had sex and fingered this girl I noticed a gap/cut near the tip of my finger where the skin meets the nail ( the point where I trimmed my nails earlier). I was wondering if I had and hiv risk and Is this high or low risk situation? Do we have mucous membranes in our fingers or under our fingernails that can facilitate infection?Should I consult a doctor and discuss PEP?
