If your boyfriend jokes about having other girls and wanting to do a three sum, would he ever cheat?

He says he thinks it's cute when he gets a rise out of me. He's been open about his past sexual and relationship history. Even had friends with benefits but he discovered that he enjoys sex and everything better in a relationship.

He does a lot of dirty jokes. He also jokes about how this or that is from another girl or (he knows that I'm bi curious but a one person relationship type of girl/loyal) about having a threesome. Even jokingly tries to ask my type.

I'm not sure how to respond to it. But if it really is just jokes, I'd like to know how to poke him jokingly back? Or should I legit be worried? He claims that he wants me in his life and to marry/have kids with me.
