Not necessarily: Canker sores do tend to happen with reduced immunity and it can be a common part of any other viral infection as well. HIV testing needs to be repeated at 3 months as it has a window period before it can be considered a true negative test. It is ideal if you get throat and mouth swabs to rule out other possibilities such as gonorrhoea and herpes

Probably not HIV: Don't assume HIV just because you have some symptoms that go long with it. Same symptoms in many other conditions, mostly minor, and the large majority of people with symptoms like yours don't have HIV. Negative RNA test is around 50-60% conclusive at 9 days; have another at 12-15 d and Ag/Ab (4th generation) test at 4 weeks. Probably also negative, but better safe than sorry.

If you had unprotected anal sex with another male, then you are at very high risk for HIV. Not this time -- but if you continue such activities with men whose HIV status is unknown, you can expect to have HIV someday. OTOH, oral sex alone is very low risk. Still, get in the condom habit -- and ALWAYS discuss HIV status with every partner, including treatment if positive.

Unlikely: Better still don't have unprotected sex again. Your long-term safety is very important
