First, the symptom you described are very minor and are unlikely to be a warning sign of hiv/aids. You don't get any immediate symptoms with hiv/aids. You even have to wait for about 6 months until after the exposure to see if you caught hiv/aids. It takes that long to affect your immune system. And then you have catch something.
I'd only be able to guess at your risk if you actually indicated the risky sex that participated in.
Not using a condom in itself is not that risky.
The odds are about a 100,000 to one against you catching anything with ordinary unprotected sex with a new partner, provided you are cirmcumcized or practice good sexual hygeine.
If not the risks go up.
If you have an open sore the risks go up.
If you practice risky types of sex the risks go up.
If you have sex with prostitutes, you are at higher risk,
especially if they are intervenous drug users, or careless about using a condom. You have to consider the risks every time you have sex.
And as I said the odds get higher and higher the more often you take a chances with risky sex.
Maybe you can give a betterr idea of what kind of sex you had?
