Hello Joe,
Your risk of HIV infection is low. Your symptons are not really
HIV infection because it only has been 3 days.
HIV early symptons are fever, dry cough, skin rashes, headaches and swollen limph nodes and they started after few weeks. The major risk of kissing is herpes HSV 1 which is not a deadly virus as HIV 1 and 2. Herpes can cause cold sore in the mouth. Check online for herpes virus type 1 and 2.
Take care!
