Hello, Welcome to HCM, I am Dr. Das
Look, blowjobs has very low rate of transmission. Because, the saliva does not contains any HIV
Now, the tests are all negative. But, you have to wait for 50 more days. Because, only a negative test result on or after 90 days from the day of exposure is a conclusive.
So, repeat the HIV elisa
4th generation after the end of 3rd month.
Hope this becomes helpful.
