Help. My boyfriend likes PDA, I don't.?

Well I told my boyfriend before we got together that I'm not a big fan of PDA. He, on the other hand, likes making out with the slobbery tongue and likes the touching of the , and that stuff. I'm okay with little kisses and holding hands, but I'm not a fan of that. And he loves telling people that we've had and the DETAILS. I think that's too much. I told him about that but he's still doing it. He said because his friends are always saying stuff about how he's not good at . Basically, he wants to feel like a man. Another thing, he told his girl cousin I used to be gay because me and my best friend kissed one time and it was a peck but it was a joke and that was last year. And now she actually thinks I'm bi. This is ridiculous. What should I do?
