Recently I visited a sex worker, and proceeded to have sex with her using condem but it came off and i think i got few thrust in during the slippage. I then changed to another new condem without cleaning my penis and proceeded to have sex with her. Now I have UTI, diarrhea, nasal congestion and a pimple like sore which the doctor told me it doesn't seem like STD. I worried that i have might have caught STD and HIV. STD results in 2 weeks time by the doctor and HIV rapid blood test showed negative at 16 days since visit. Please advice. :(
