Hello, i recently discovered white patches on my tongue and 2 red bumps at the very back of my tongue. This worry me because as i have checked on the internet, it means that i might have the HIV. I am only 15 years old and has never done any sexual intercourse with anyone before. Well, as an experiment i have tried ejaculating in my mouth before just to see how it tastes. Also, i have masturbate almost everyday through my pants and when i ejaculate, i just let the semen stick on my pants until the next day to wash it. Will any of this be the cause of HIV? Do i even have HIV? What should i do?
