As driver said,you had a risk. I'll try to help you relax a bit.
As a top, it lowers your risk, as does the brevity of the exposure.
The chances are (statistically) he didn't have hiv. And IF he did again, statistically, you are most likely not to catch it.
Also, symptoms start all at once at around the 4 weeks. Not bit by bit here or there. They come all at once and you are really poorly with it. It's not a bit annoying, you are very poorly.
Get a test done but I'm confident it'll be negative.
Never gauge the infection, using symptom's yardstick. Symptoms do not mean much and often misleading.
Get yourself tested any time now, 4th generation HIV Duo test is conclusive now, collect your report and move on with your life. You had a risk and this is the only way to rule out the possibility.
