Would you feel uncomfortable with your husband's best friend talking to your husband about porn?

I don't watch porn and my husband doesn't watch porn but he has a best friend who does porn. Mainly only fans with his girlfriend. I guess things haven't been going well in that department because whenever he's hear it feels like he's always talking about their porn which he refers to as his "job". I've spoken to my husband about it but he just says they've always told each other everything. Today he was over and talking about their BDSM scenes they've been doing together for only fans and when I mean things don't seem to be going well in that department he was talking about how he feels like she takes it too far so doesn't seem like he's even enjoying it anymore. But he was going into detail about it. He was telling my husband how she's really into knife play and that's why he has so many cuts all over his thighs and saying it's her new kink and things are getting a little too much and how he thinks he's gotten in a little over his head. They started talking about safe words and how his girlfriend isn't really a safe word person and my husband was saying how he isn't a BDSM person but he's pretty sure safe words are mandatory in BDSM. They talked about this for an hour until my husband subjected they play video games to get his mind off of it. I know I can't control what other people do. I also know I can't control who my husband is friends with. He wouldn't let me regardless because they've been friends for so long. But do they really have to talk about porn so much when he's here? It makes me uncomfortable.
