Last week I shared a couple cigarettes and a couple joints with an uncle of someone I know. He looked looked unhealthy, had only 2 teeth, and used a wheel chair. When I asked him why he was in a wheel chair he completely avoided the question and would not answer. I am wondering if there mite be a possibility that I may have contracted HIV from him concidering the fact that he didn't have teeth and mite (not sure) have bleeding gums or something. I just want a general opinion on my situation from someone (to embarrassed to ask anyone I know) as to what they think the probabilities are considering the circumstances I described above that I may have contracted something. I am not even one hundred percent sure that that man had AIDS, but he sure looked like it very convincingly. (Although he was able to push himself on the wheel chair) And also, how long should I wait to go and get tested for HIV just to make sure? Thanks.
