Is this disrespectful

My bf told me today that his coworkers went to a restaurant today and his co-workers said that the waitress told them they think my bf is cute and asked for his phone number.

Then he said that his one co worker told him that he “can go back in there and get some p*ssy”

And they all were laughing.

When he told me about it, it kind of upset me. I found it disrespectful because he’s in a relationship with me and we even live together. I know it was just a stupid joke, but I don’t think it was right.

My bf is mad at me for being upset over it and said his co workers know about me. And they were just joking.

Do you think it was disrespectful and rude ? Or do you think I’m overreacting?
