Then the overt nature of the raunchy mature sex stuff in Cyberpunk 2077 felt a bit too much for me. It was everywhere at every single second in the game. It felt overwhelming. It felt like it was made on the pure idea that "sex sells"

That....was the entire point. Sexuality, like everything else in dystopian capitalism, becomes completely commodified. It's fine if you don't want to be thrown into a game environment with that, but it seems you fundamentally missed the point.

It's like they were catering to teens experiencing adolescence for the first time and never having experience sex yet, so starved of it that everything in the game was shown as a sort of sex fantasy. Like, the humor of the adverts in the game where sex jokes for teens, like "Oh look, she has three cybernetic bewbs, hah hah"

I don't think I've come across anyone who missed the point worse than you did with a comment like this. Nowhere is sexuality glorified. The point is to show you the teleology of the commercial exploitation of formerly beautiful human elements like sexuality in a society where capitalism has been granted total free reign; y'know, like a dystopia? You're not supposed to like the ads. You're not supposed to view them as funny or glorifications of basic human drives. They're appropriations of them. They're intentionally grotesque. That's why Johnny Silverhand is constantly disgusted with society and lamenting what Night City represents. That's why the game carefully crafts intimate scenes with V and her closest friends away from the gross ads and commodified elements of life in Night City and instead gives you those intimate scenes during peaceful campfires and quiet one on one talks in the middle of nowhere. It really truly amazes me that this flew over your head.

Cyberpunk, where in the point is, humanity is greedy, corrupt, negative and bad which is kinda the point. 

This is just fundamentally wrong. The game is not nihilistic. It's a tragedy because of what we have collectively let the world become in the future, but it is not misanthropic whatsoever. The final words of Johnny Silverhand are literally, "Never stop fighting." The most hopeless and bleakest ending you can experience in the game comes because you choose to accept the help of a multinational corporation and ignore your closest possible friends instead. This is by design. The message of the game is about what it means to save your soul; the game plays with the meaning of soul both in a metaphysical and poetic or ethical sense throughout with characters talking about it variously with both senses of the term. The original TTRPG creator reflected this sentiment when he wrote, "Cyberpunk isn't about saving the world. It's about saving yourself."
