Ron, actually I believe this is similar but not the same than hiv. I have had just a few sexual partners, all women, most of them were my girlfriends and other casuals encounters, I could suspect about just one of them. Second, my last risk was using condom and was too short, the problem is that I was drunk and there are crazy people wanting to cause damage to others, you never know, but, I had a lot of negative test of antibodies and indetectable PCR, so I had to asume that this is not about hiv, specially thinking that there´s not cases of rare strains of hiv in southamerica (I´m from there). Finally, I have to say that this is not my first time dealing with strange symptoms after sexual encounters, I had one before with my ex girlfriend, after that I have some chronics symptoms like diarrheas, dry mouth, white tongue, dry eyes, etc. And last time 3 weeks after having sex with some unknow girl I had exactly the same symptoms than ARS, and I steel have some chronics issues, but again, I dont think this is about hiv, my elisas show that, my CD4 are in normal range and theres no antibodies, no antigen and no evidence of virus in my blood with the PCR. So, I believe this is something else, some other virus or bacteria and I specially believe that for some reason we are more susceptible than normal people and existing so many virus out there, they can havoc our body easily.
