Symptoms like those that your report (sore throat, feeling feverish, burning eyes, feeling weak/tired, headache, grumbling sounds below your stomach, and fast heart beat) that occurred a few days after the sexual intercourse can’t be symptoms of AIDS. Symptoms of AIDS are various and include those you describe but they don't appear so soon after possible contact with HIV! After exposure to HIV, there is a period of incubation (clinical latency) characterized by a time period without any symptoms. It is a part of the nature of the disease to remain hidden in the infected cells (T4-lymphocytes).The duration of the latency is different in different people and can range from several months to even years. After the incubation period comes the prodromal period, or period of initial infection which manifests with non-specific symptoms (fever, lymphadenopaty, rash, headache, tiredness, nausea, vomiting, diarrhea, night sweating, painful muscles and joints,) that are also present in many other infective diseases. Some infected people, however, may have no symptoms during the initial infection. After the prodromal period, comes a period of developed disease (AIDS) that manifests with prodromal symptoms, mentioned before, and is accompanied by symptoms of other opportunistic infections, tumors and brain illnesses which are able to invade the body due to a totally destroyed immune system.
Your symptoms appear to be more like symptoms of the common cold than of HIV/AIDS. Nonetheless, you can go to your primary health doctor for an examination and therapy. Even if you have been infected with HIV, an infection can’t be proven so soon afterwards because the immune system needs time to create antibodies against the disease. Antibodies need 6-10 weeks to be created (seroconversion). You can take an HIV-test now and another one after 3 months.
