Should i be tested again after 6 months negative?? hiv?

are you serious, You kissed a girl and think you may have contracted HIV? Dude, you will not get HIV from kissing. Even if the girl had AIDS. No way No how. You are negative for a reason, you did not have an HIV risk. You may want to seek the help of a mental health clinic. you may have something going on, but HIV is not your problem.
