There is absolutely zero reason to play a game the Devs intended if you don't like it.
I can think of a few:
-Miss optional events, if you don't need to make money or complete optional quests, you most likely will skip a lot of extra sex scenes and interesting events, some games have the best content set on optional side quests...
-Break the game, if you can kill bosses you werent supposed to, now have access to areas you shouldn't be exploring yet, so you might end up wasting a lot of time exploring without finding a single quest only making you waste more time and sometimes not being able to complete the game because of that.
-Diminishing return from the intended pacing and buildup, there is usually good reason to create obstacles during gameplay, the sex scenes can feel that more rewarding when you worked for them, if you remove all challenges and sped up this process you will barely care about the sex scenes.
If you truly don't care about the game where missing everything I mentioned wouldn't matter, why even play it?
For sex with no buildup there is a massive resource called the internet where you will find loads of it for free with no gameplay wall... I just find it weird to have people playing erotic
games that hate the "
game" part.
