The Typhlosion story in-game is a 3-line-long poem about a non-descript Pokemon that masqueraded as a human, and humans masquerading as that Pokemon with its hide.
Obviously the sex stuff doesn't need to be in the games because it's designed for children, but the fact that any of those stories were considered for the final product, the same product that has the story of Pokemon and humans marrying at one point in time (in the JP version, because localization) has to speak to some degree about what other kinds of cautionary tales would be told in this fictional universe.
It's an interesting conversation to be had. Kids aren't gonna need to know or care, but by the time D/P was out, the people who played RBY were growing up or growing out of Pokemon. Someone (or multiple people) probably thought of that and said something along the lines of "why don't we include loosely mature themes while catering to the age rating and tuck them away in an in-game library for the people who want to find it?" I'm sure they didn't want the uncensored drafts of them to come out, but what we've seen over the last few days, is the pure essence of worldbuilding, present in the Pokemon games.
