The problem is that sexualized media sells and is in high demand both for males and females.
When Shades of Grey is the best selling novel of basically all time in most western countries that sends a signal to publishers who create media.
Nintendo wouldn't have dreamed about releasing Fire Emblem or Xenoblade Chronicles 2 in the US or Europe in the 90's but sales trends have showed them that this is what the audience wants.
Because the moment they redesigned Fire Emblem and put the emphasis on the cool looking slightly edgy characters the sales went through the roof.
I imagine that a lot of straight guys would quite quickly get fed up if male characters were suddenly all stripper-esque in every movie or game. Yet that's what women have to deal with all the time.
Like how in every super hero movie the bulkiest guy has to remove his shirt to show his muscles or fulfill a 'save a helpless innocent girl' fantasy at least once in his story arc? The pandering is included to get viewers from all genders to the cinema.
The creators of most media have really nailed down how to pander all audiences. I've known girls who played Assassins Creed 2 only because Ezio was so 'hot' and guys who play obscure JRPG's because of the girls on display.
Movies like The Hunt for Red October were simply about a US navy officer and a Russian defector. Had it been made today the Russian defector probably happened to smuggle his hot Russian wife aboard his ship that the US navy guy has to save shirtless in the end for no reason.
If you don't include such scenes in your movies you even get criticism. Like in Dunkirk Christopher Nolan showed how utterly fucked the British boys send to fight in France were and all he got back was: "Why weren't there any blacks/hispanics/asians etc. or women in this movie?"
Most people don't want to see regular folks in their movies and games. They interact with normal people on a daily basis. In their fantasies and entertainment they want super models and well their fantasies on display - not reality.
So creators of media just go down the list
- Some eye candy for guys
✔
- Some guy who's an asshole but turns out he's actually all right in the end and looks pretty hot
✔
- A strong female character that stands up for herself
✔
- A seemingly boring good guy that betrays everyone in the end
✔
etc.
So if you want to change all this you will have to get people to give up their fantasies which is never going to happen. What you can do is remove the excesses and stuff that wouldn't fly if it was in the latest Star Wars movie.
Like underage love interests.
It's funny how these trends change over the years. In the movies of the 80's it was all about guys setting aside love interests and not being tempted to enter relationships in order not to get distracted from their missions and goals.
In the 90's it was mostly young guys hooking up with slightly older women (most of the time their supervisors or bosses).
From 2010 or so forward it's mostly older guys hooking up with much younger love interests. Old guys probably became a trend because women decided that George Clooney was the most attractive man.
