I am an adult and I do this too, but not because sex bothers me, it's because the vast majority of sex in mainstream media is incredibly stilted and embarrassing to watch. Cinema has had over a century to try to portray and capture actual relationships between people and still hasn't even come close to accurately portraying attractive, affectionate chemistry between two people.
The fact that in mainstream programs and movies, the lead characters ALWAYS have to have this "enemies to lovers" dynamic makes me gag. It was funny once or twice, but that's not remotely how real people have real intimate relationships, so why does Hollywood lean in SO HARD to the same trope of the sassy female proving she's as tough as the rugged male anti-hero and they always have to have this weird battle-of-wills where they have separate goals and can't show affection openly to each other.
It's no longer interesting. I have seen porn with better, loving, attractive relationships.
