Boyfriend called me a slut because my ex was talking about sex with me on a podcast

I once dated a musician about 5 years ago. We have a very sexually open relationship. We had threesomes. He watched me kiss girls because I'm bisexual. He himself said he was "straight" but confessed some curiosity so I helped him explore that sexuality. We didn't end on bad terms. My boyfriend found a podcast my ex went on 3 months ago and got pissed because he was talking about sexual stuff that had to do with his ex girlfriend. He didn't name me but it was clearly about me and he didn't really go into detail. Just said that he had a sexually open relationship with someone and that if it wasn't for me he may never have had the confidence to fuck a guy and I helped him figure out his sexuality. If anything he went into more details about sex with a guy for the first time than he did about us. He's bi. My boyfriend told me to message him and demand he take that down. I said it looked like it was on someone else channel and he was just a guest and it was from months ago. He said I'm a slut who must love a guy talking about fucking me. He does shit like this constantly. If he even thinks a guy likes me he blames me. Should I try reaching out to him to see if it can get pulled? The podcast seemed sponsored and I heard you can't just take down a sponsored video plus it wasn't even his pod. I haven't spoken to him in 5 years but just don't want to fight with my boyfriend. He stresses me out.
