(I cut my nails two days before this incident and cut them too short and I can see a tiny amount of blood under my fingernail today, a day after the incident) I was fingering a girl and I noticed that my finger started stinging and I realized that I cut my nails too short and i did have a wound under the nail. If this girl was HIV+ is there a chance that I mightve been infected? I know that people may say that i can only get it if it is an open wound, however, i did feel my finger sting so does that mean the vaginal fluid made contact with my blood?
