Sores in my boyfriend's mouth and one on his penis...
Hi so I'm just finding out that sometimes my boyfriend gets sores in his mouth. He gets them in the roof of his mouth and he has one under his tongue. He also has one on his . I did research and found it could be a yeast infection, herpes, and HIV... I don't think I got herpes or HIV because I've only had sex with one other guy and he was a straight up virgin, I'm 100% sure on that, and me and my boyfriend both have that new shot that's suppose to protect you against sexual diseases. But I thought I had a yeast infection at one point but it went away... Any way I don't know what it could be... PLEASE help! Only answers that are like super sure. No guesses please. I;m worried! And if it is a yeast infection please tell me how to get rid of it!
