ok so my boyfriend called me saying that he got bumps on his part and claiming I have something! I'm super confused because that was the first and only person I have ever been with. I don't have anything. Yesterday we had unprotected sex and now he's claiming to have bumps. I'm super confused someone help me!?

There is another problem he won't tell me what the bumps look like.. I called him and told him it was most likely an infection or irritation but not an std. I don't know how to help him because he kept claiming I had something which I don't. we've been having sex for almost a year and we were both virgins. He's being to stubborn. I don't know what to do now
