It could still work with Bernard honestly. Remember the mini quest Bernard has "More Potions" where he needs more Restrain Potions. Hyao could edit that that small quest. He could make it work via dialogue options where the player could suggest using Logan to get his rocks off instead- that way it's repeatable. But we should be able to tell to him to just stick to potions as well, like how we could suggest Korg to have sex with Logan or tell him not to. So there's player agency.
Plus I'm betting that his werewolf urges have heightened his libido, he says so himself. So maybe we can assure him that it's okay for us, like he is okay for the player to slut themselves as well. I mean he does also get a little bit turned on seeing the player get all slutty in the forest during that werewolf event.
