I doubt that talking to her DH about his porn usage will produce any deep, meaningful revelations.
Men watch porn because they like to see (usually young) women naked and performing sex acts. Simple as that most of the time. It's like asking someone why they like chocolate and expecting a philosophical debate.
Yes, men can turn to porn if their sex life has diminished or dried up but that's a bit of an old trope. The fact is that porn is stimulating, readily available and addictive. It is more likely to cause problems in real life sex than to help or enhance it.
Now he's found it (and he's probably been watching it for years) he's unlikely to give it up but he's very likely to make promises and say just what the OP wants to hear.
Porn is demeaning to women and many of the women in the content are abused or trafficked. It's become a big problem with young men whose views of women and expectations of sexual relationships are informed through that medium.
Most women will see their partner watching "perfect" 20 year olds performing on the screen and will assume he is drawing a comparison to her body. That's natural and psychologically very damaging.
