I have hemorrhoids, and sometimes the hemorrhoids would be bleeding. Yesterday afternoon, I was playing basketball for two hours. When I get back home, I found there was a lot of blood on my underwear, which means my hemorrhoids was bleeding when I was playing basketball. As I was playing the centre in the game, my butt had a lot of touch with the competitors in the basketball game. My worry is like this: if someone is HIV infected among my competitors, and my butt touched his bleeding body(my hemorrhoids touched his bleeding body), will I get HIV through this way? Please help me, I am extremly worried.
