Hi there. So if you had AIDs (you dont), the HIV test would still pick up the HIV itself as its still there. Often, not always, it will take at least 10 years for the AIDs to set in. Also you state you had protected sex. If it was protected, there is no chance of HIV at all.
Your man boobs, white tongue and dry skin is no symptom of an STI and with a 2 year gap, any symptom would have shown its face by now.
You DO NOT have HIV.
