I haven't seen this in the design document, or mentioned, and I never actually used one but I felt that I should just put this out there.
since a temple is being added, maybe there could be a meditation, prayer function in it that allows PCs to reduce libido, and or increase willpower, like a preist or monk helping you go through a mantra or prayer that causes the PC to lose a point in libido or gain a point in willpower.
Sure, game could totally use something like that. Shame it's so late-game.
