I don't think it's presumptuous to attribute it to your mindset when what you're saying is your opinion. My, similarly personal opinion, is that i don't perceive myself "less catered to" on a path where i choose for the characters not to fuck everything that moves. Or catered more to when i choose to play a path where i do.
All is easy for those who don't have to put an actual effort in producing the game. What the game actually does is reusing some of the content in order to provide the player with larger selection of characters they can pursue. Because the author doesn't have means to produce even more unique content she already does, in reasonable time.
Mind you, this bigger selection of characters doesn't mean skewing in any particular way, because the decision how much of it you want to see in single playthrough is, again, completely yours. Whether the player wants to juggle between a few characters, or focus on just one or two, that's all on them. The game itself isn't influencing it.
And you seem to be making a big presumption here, about the nature of sexual content in the game. Because for all we know a large part of this content is actually made with "romantic path" on mind first, and then simply reused for the "slutty path" which effectively gets some cloned leftovers.
