	/// This patch enables cum-eater pawns to drain cumflations for more fertilin drain by passively having sex.
	/// It is hooked after RJWs Change-Psyfocus so that pawns that are having prolonged sex (e.g. by overdrive) can fully drain the cumflation over time.
	/// 
	/// It is conditionally loaded only when LicentiaLabs is enabled, as this is the necessary source for cumflation-hediffs. 
	/// The patched function is: [HarmonyPatch(typeof(JobDriver_Sex), nameof(JobDriver_Sex.ChangePsyfocus))]
