Dear m.prabhu, being hiv
positive and to land in AIDS
tkaes very long period and the question doesnt arises if you had protected sex. dont worry if test are also are negative whats the point in thinkking og hiv. diaorrheoa can happen to every one if it vud not have responded . for months then you can think of hiv . but in your case with this episode my opinion will not favour hiv again finaaly you get hiv done for your satisfaction after 6 months of exposure till then relax. enjoy life. it is all your guilt feeling of having sex with friend .
