Confused

So this boy I had sex with about 2 months ago told some people (except me) that I left him “burning” even though we used a condom. When I asked him about it he said he never said it. I’m confused as to whether to go get checked or don’t worry about. I’ve had a disease before and got rid of it but now that I think about it I do have alot of unprotected sex with different people. However, my area feels normal and its like nothing is wrong. I’m not sure what to do😩
