Welcome to the forum.
You had accurate replies on the community forum. It is impossible to catch HIV in this fashion and you do not need testing. If the virus could be transmitted as you fear, HIV/AIDS would be a hundred more times as common and would not be classified as a sexually transmitted infection.
You correctly described your only significant health problem in your question on the HIV International forum a week ago, and I agree exactly with Dr. Cummings' advice. Irrational fear of contamination is a mental health symptom, sometimes the first step toward serious psychological disability. (For an excellent example of where it can lead, rent "The Aviator", the film biography of Howard Hughes.) Please seek professional counseling about it, which I suggest out of compassion, not criticism.
