Omg, Help Me. Help Me Please.

I'm a 19 year old male. Here is my story.

The incident happened on exactly nov 5 2006.

-------------------
i had unprotected oral sex with a female, we also had protected vaginal sex, but that was all.

After a couple of days, I started to notice my testicles started to hurt, like almost overnight. They were swollen to me. And it was hurting alot. Also I notices a little rash at the top of my pubic hair which seemed to dissappear any time I was at the hospital, the doctor could not see it. But I noticed it at night and after showers.

Although the chylmadia and gonnorea tests came back negative, the doctor treated me anyway, with cipro and doxy. Also during this period, I noticed a white-ish discharge but not when urinating, only when I was taking a caca. When I forced it out. Not while pissing. Also, I experienced some kind of itchying when it all first started but that seemed to have subsided. Also, I noticed my urine smelled very different like worse and so did my genital area, still there but subsided a little


after this, I got very worried and saw a urologist, he did another urinary test there and then, which took like 10 minutes? He left and came back and told me it was negative? Did he really do it? Anyways, he said my testicles felt alright and that the discharge was something called prosatal fluid or something like that and that I shouldnt worry, I dont know what to do...'



later on everything subsided, I havent seen the discharge for a while, but now, it seems like after I urinate, I feel a sensation in my penis that seems to last for about 45 minnutes. Everytime I go again, it comes back. I really dont know what to do? Help?

update/
question
----------

i have been feeling extremely weak and tired for the past 4 days straight, when I sleep and wake up I feel even more tired than before, I went to the hospital the doctor took some blood samples to measure blood count. I'm scared. I feel very very weak. Also I did an hiv on monday and the result was negative. I'm wandering if hiv manifests it's early symptoms, it should be showing positive by now if I was infected right? It's been approx 2 months since my incident.
