Casual reminder that Game Freak and The Pokémon Company have both confirmed in Black & White version and in Legends of Arceus that marriage between people and Pokémon were extremely common because they were both once the same thing. It can be surmised that humans having sex with Pokémon was and probably still is a common and legal practice in universe.
When I remembered that Machamp can be female with virtually no change in appearance from a male one I can't decide whether that is raw nightmare fuel or the start of a new hyper amazoness femdom fetish.
Sex with Pokémon & breed them.
