Ur welcome. Everyone playing the game should have the potion thread bookmarked; that poster, ladywhiskers, saved everybody here a heap of time & nerve. Even went analogue on that sh*t, PDFed & printed the list on paper so I don't have to alt+tab no more^^. Nice weekend & happy potion brewing.
EDIT: If you wanna mess with character traits/genetics directly & effectively and are not above cheaty moves, edit the save files. Each char has a field with all the traits you see in-game on the "character sheet", like the physical features (which is the part potions can change), but also stuff that's set on char creation/spawn like personality & aquired perks like "sexy" or "scary".
Best thing about that list, you can use the names on there as-is when editing a save, the physical traits are called the same in the save data as in-game, no clunky ID-number or -code. And if you're so inclined, you can also mess with their combat moves with "learned abilities" (these are also named exactly like they are in-game; "Capture", "Guard" etc), you can add/remove sex positions in "eroMoves" (names the same as the pink & purple books) and their sexual preferences with "eroTags liked/hated".
