I am a guy and I fingered someone who is HIV + via the anus with no lubrication, although I had no cuts on my fingers that I was aware of , my finger nails can be quite long sometimes and we didn't use lubriation, just spit. We didn't have sex because we didn't have any lube although we had condom we needed lube. I would have been top. What is my risk to the infection? I know he was HIV + as we met just 8 weeks ago. I didn't know his status at the time.
