Is there any reported case of hiv aquired from deep french kissing , do i need tet test after deep kissing ?

No way to study it: If one person in a couple has HIV, then the other person might catch HIV. So, the most important question is, "Who has HIV?" If neither person has HIV, then French kissing all week will still not lead to any HIV, as you can't get something from nothing. Adults interacting with others may do annual HIV screening. Non-bloody oral activities are not expected to transmit HIV unless people are unlucky.
