do you wanna include non canon stuff or just canon stuff? cause in the case of both canon and non canon I can think of 4 scenes, the 3 already mentioned by Khaylis and Saber, and the Halloween event from forever ago where you screw with all 3 werewolves and Korg.
and another semi weird scene/scenes that could count, you can technically sleep with him when you capture him and he's in the prison if you either didn't choose Logan or never gave him the wolves bane and let him go wild in the forest.
also you can seduce him when he's fighting you as werewolf Logan/red werewolf or whatever the enemy name is lol.
