>>55728154Sex is canon in the Pokémon world. Just cause they don't mention it doesn't mean it doesn't exist. Married couples also don't openly talk about their sex live.
The SV protagonist is a ~13 year old kid who befriends a bunch of attractive peers, it's not weird to wonder if they ever got intimate with each other behind the scenes.
Carmine even asks Arven if there's any "special feelings" in the Paldea friendclub and calls him a "poor, innocent thing" when he just answers something about their trip to Area Zero. She clearly asked if any of them were dating, and teenagers who are dating have sex. The implications are all there.
