Now with Pokopia's success, you'll start seeing Ditto be actively pushed in commercials and marketing buzz, alongside the other Kanto greats like Gengar.
Also, the vast majority of the public associates Vaporeon with sex thanks to the copypasta. What makes you think they wouldn't associate Ditto with sex when its literal core function is being "the Pokemon that can produce eggs with almost all other Pokemon"?
