Some style trends are good some are bad.

 For example,

an old style trend is to have bikini or panty straps rise high, it was an 80's style, I think. It might be interesting or fun to do, but this is not attractive/titilating, and so the trend died, and that's a good thing.

likewise, having a thin pillar(shape) of pubes is not attractive. 

a lot of porn is made by people who don't consume porn, and women, and therefore DON'T KNOW, what is attractive and what isn't. 

I'll give another example.

Some people/women don't have a sense of time and place. They think it's hot to take a nude photo at the side of a river. But from the perspective of the man, let's use empathy now, the river is not a comfortable setting to have sex at.

and certain women have a better sense of time and place, certain women are better photographers than other types of women.

Another,

Some people/women don't realize, DON'T KNOW, that shyness is unattractive. Indicators of shyness are squinting, trying to cover up despite taking clothes off for the camera or a person, keeping legs closed despite having clothes off for the camera, or presumably, a person.
