Point taken. However, I still see another possibility when creating NSFW art. Let me compare two typical pictures.
This is a seductive Princess Celestia, spreading her pussy wide. In this picture, the pussy is the focus, and the artist does a great job detailing it. The two openings inside the labia majora, the clit and the texture are all carefully depicted. I believe when you are talking about adding details to the genitals, you are referring to this kind of art.
The picture below, on the other hand, is a typical NSFW work built up with both sexiness and cuteness.

We can see in this picture that Pinkie Pie is making a cute face, lying down with her strawberry marshmallow front hooves holding her hind legs up. With her slit on the crotch this is obviously an NSFW work, but to arouse people, the artist does not only focus on the genitals. He tries his best to make the texture of Pinkie’s body fluffy and soft, especially her chest fur. Not to mention her always fluffy mane. This little pony gives the impression that if you give her a naughty cuddle, not only your boner but also your arms surrounding her body and your face rubbing her face will enjoy the moment. Basically a cute little line does the job of maintaining the picture’s adorableness by making Pinkie’s pussy look soft and delicious.
I like both types, but the second type really needs more attention.
