Because shaved is just better, not ;-)
Honestly, let them make their game, I like the girls as they are. In some games they shave, in others they have a beard, everyone to himself, but don't change the girls!
I agree, I too wish at least Ann could keep her original pussy hair and that there could be more of it (Not just for Ann but for other girls too. And not just in this game, I confess I would like hairy beavers in all of the games I like). But we can't always get what we want and I prefer getting regular updates and new content. Especially if the hair options lead to multiple new/extra renders.
However, I heard TTrick has a trick up his sleeve
and that he (due to great programming skills) can position things on bodies as a choosable extra flavor to a render (this came up in a discussion about adding tattoos to Ann or others. I am opposed to tattoos, I really dislike em). If so it might not be that hard to allow for player choices (keeping fingers crossed). But story progression first, all of that should be flavor content at the end (if it is possible and not to taxing for our beloved developer).
