I've thought about this before, pubic hair in TiTs that is. I reckon, with my very limited knowledge of coding, that it could be added in a similar way to the royal mane. Use one of the values to determine hair type, one for length and maybe one for style with some additional work being adding several changes/ variations on vag and dick base descriptors. What would have to be written would be the appearance screen text for each hair type (hair, feathers, tentacles etc.) at each length (probably just have four to simplify like none, trim, hairy, unkempt) and for ease of mind just have style override the length in appearance and just take it for granted that if you have a Brazilian it's not a jungle down their. Then write all the additions to the current base descriptions so that pubic hair gets mentioned in sex scenes and all you have left to do is convince a coder that this isn't a waste of their time and convince fen that even though he said "leave it to your imagination" you're not that imaginative and therefore this should be in the game.
