around 2 minutes, the girl touch the head of the penis. I am worried that her hand have her vaginal fluid. If her vaginal fluid contact the head of the penis, is there any risk?
3. I also put one of my finger into her vagina for 4 seconds, so i think there is her vaginal fluid under my nail. After a day, I use that finger to scratch my nose and my nose was blooding. Can the virus survive that long? (After I had sex, I also have a bath with shampoo, but I am not clear that under my nail is clean.)
1, If the head of your penis was covered, there was no risk of transmission
2+3, The HIV virus becomes inactive as soon as it comes in contact with the outside environment so transmission cannot occur this way.
