obscene conversations.

My SO loves listening to podcasts (from a specific person) and sometimes I will too because it can be interesting. 
But how would you feel if all of sudden all they are talking about is "tight pussies"? 
Literally that's all that's being said.
"Oh yeah these women can have surgery for tight pussies because the tighter the pussy the better"
"If she doesn't have a tight pussy, then she's gone cause right pussies are only way too go"
How would you react to your SO knowing he listens to this DAILY?
I find it so disrespectful because thats such an obscene conversation in my eyes.
So when I brought it up to him about it being disrespectful he immediately said "I'm sorry you can't handle adult conversations because they're just words. Grow up."
