Hi there, I am 20 year old and I am having a yellow semen for over a week now, my friend got an STD and I asked him about its symptoms, he told me that when he pees he feels so much pain that he could punch a wall, now I never had a pain like that just a little burn when I pee, I did have sex last january 22 and the yellow sperm just came out last february 11. please help
