Symptoms cannot be used to diagnose HIV. The symptoms associated with a new HIV infection are the same symptoms associated with a large number of other illnesses. You had a risk from having unprotected sex, so you should test. A DUO test (Ag/Ab) at 28 days post-exposure will give you your result.
I'm not sure what you meant by the handshake story, but that would never be a risk for HIV, if that's what you were asking.
