My man doesn’t like dirty talk

I tried dirty talking during sex which was really outside of my comfort zone, just because I wanted to spice things up. The next day I asked if he liked that and he said (very politely) that it made him struggle to focus. Does anyone else’s man not like dirty talk for this reason? My man has delayed ejaculation so I definitely understand he needs to focus but I was taken aback by him not liking it.
