If you watch a scene and soon forget about it, then you probably won't rate it highly. The best scenes are those that you recall with pleasure and remember for a long time in a good way.
Because it's not much of an experience if you soon forget about it. The best experiences are those that you remember for a long time and repeatedly enjoy them by recalling them with pleasure.
Recent research has found the people's memories of their experiences naturally fade over time in a specific kind of way. People forget the visual and the miscellaneous details. But they remember the meaning of what happened. After a while, people only remember the meaning and not much else.

This means that a porn-scene which doesn't have much meaningful interaction is very forgettable over time. This scene might be hot to watch for the time that you are watching it. But you won't remember it much afterwards. And you won't rate it highly, when you look for another scene the next day or the next week. You'll be looking for something else and not a similar kind of scene.
So, how exactly can you add meaning to porn-action and make it memorable for a long time?
I think one way to do it is to provide some specific reason and motivation for why the cocky guy does it this way or that way with his lady.
You should be able to ask the question why the guy did this or that? And have an obvious answer that's specific for the scene and not just a general answer, such as "Because the lady is hot". If the answer is the same for every scene, then all of these scenes get mixed up in your memory and you don't remember much any of them.
A good example of a very memorable scene for me is from a 1980s film. It was an anal scene for a lady with a hot butt. She did it in doggy with the guy. He banged her nice ass long enough and hard enough to pull out and cum on her sexy bum. And as he was beating his cum-coated cock on her ass-cheeks, a female voice said loudly "Put it in!". It was a close-up shot, and it wasn't obvious who said it. But from the viewer's point of view, it looked like the anal lady was the one who said it. The cocky guy hesitated, as if he didn't know what to do. But the female voice once again said firmly, "Put it in!". And the guy at his point aimed his cock at the lady's semi-gaping asshole and plunged in his pole. And he didn't stop half-way. He kept going until he was all the way to his balls inside her nice ass. And the lady's response was a loud and long "Aaahhhhh!". Which expressed some some surprise, strain, and pleasure. The guy didn't exactly put it in. He plunged it in, perhaps in a way the lady didn't quite expect.
This interaction wasn't a story-line or even some kind of difficult acting. The lady's voice might've been added after the scene was made. Because you couldn't actually see her say it. It was a close-up shot, where you could only see the lady's ass, her pussy, and the guy's cock.
The guy and the lady had some sexual communication that led to her penetration. And that's what made the scene so meaningful and memorable.
I've remembered this scene for decades. And I enjoy recalling it every time. I think more scenes like this should be made. Because there is no comparison in the amount of enjoyment you get between a scene that you watch and forget and a scene that you remember for a long time and enjoy recalling it every time.
And it's not difficult to make scenes like this. Because you don't need to show the lady actually saying it. Some other lady can potentially say it and have her voice added to the film afterwards. But it will look to the viewer as if the lady in the scene said it, and the guy responded accordingly.
Verbal sex communication between the lady and the guys during their sex-action is what you need to make the scene more meaningful and more memorable. Because the thing that people remember, after they forget the details, is called 'semantic meaning'. And semantic meaning is expressed and remembered through language.
The lady and the guys need to verbalize their sex-action, while they are doing it in a corresponding kind of way, to make it memorable for the viewer.
