Is it normal for a boyfriend to call his ex "sexy" and try to brag how all of his friends wanted to get with her?

So my boyfriend has a history of saying such remarks. For example he told me how beautiful his ex is as compared to my ex whom he thinks was average.

Then recently he said that one of his other exes was so sexy that most of his friends were attracted to her in a sexual way.

I found this weird and it threw me off. But I'm not sure if I should call him out as he might think I'm jealous which I'm not because I've never seen his ex.
