Hi.. Two months ago I make protected anal sex with a sex worker. The sex worker gave me the condom and opened it and also put lubricant on it. I ejaculated inside the condom after two minutes without break in the condom as I know.. I also sucked her nipples and I felt a slight bitter taste from one of them.. I tested for HiV and syphilis after nine days.. The tests came negative.. I have no symptoms unless a small ulcer in my mouth.. Should this episode need test?
