As I have said innumerable times on this forum,
symptoms never are a useful indicator for or against new
HIV infection, because even the classical
symptoms of HIV are caused much more commonly by other viruses and illnesses. (Read just about any 10 threads at random for more discussion.) Anyway, your symptoms don't suggest HIV (see below). You're probably a better judge than I am whether your genital area symptoms are due to a recurrence of your prostate problem.
