Will there be an option to turn off pubic hair?
No. As I replied some time ago to another comment:
"If I did that the game would have the same size as a triple-A game because all the repeatable events (99.9% of the scenes with the girls out of the story) would have to be adapted depending on whether they have pubic hair or not. So, in order to give variety, I choose what kind of pubic hair they have or not depending on the girl (for example Mara and Anna are always shaved). So unfortunately it's a rather complicated option to implement!
Besides, I personally like that each girl has a variety in that physical aspect because it gives them a unique "touch". I usually spend some time choosing the right one for each girl according to her body and personality :P"
