Unfortunately, that's just how tags work here. It works both ways though. If you search for pregnancy tags, you're going to have a hard time finding a game solely about pregnancy, but if a game has something like an NTR tag or something you don't like, then it's a good thing it's tagged as such regardless of how short/few scenes are relating to said something.
Which is why I began with "petition to".
Besides, a random NPC slapping the behind of your virtual girlfriend once (which is pretty much the equivalent of "pregnancy" in this game) isn't going to turn people away in disgust, even if they don't like NTR, in which case even NTR tag would be unnecessary. "That's just how it works", sure, but the point is that's not how it should work.
Besides, F95 needs a functional system because I can search for pregnancy tags
but I'm going to have a hard time finding
a game, let alone a game revolving around it.
Searching by tags is madness.
