About three weeks ago I had an encounter with a female. I fingered her and with the same hand I rubbed her breast. I licked that same breast but didn't notice any moisture with vaginal fluids. I am wondering if licking the breast with dried fluids can cause HIV transmission. Also I washed my mouth out with water but used the same hand which I used to finger her. Would this cause transmission as well? I took a 3 week rapid test and it came back negative. Also is this 3 week rapid test conclusive from my possible exposure?
