@cjduke: So far as the sex stuff goes, I should say that I managed to play the game without seeing any sex scenes, so there's definitely the ability to play Geralt in such a way that he isn't.
And for the windows, I wanna say that in situations like the Baron's office, where I noticed the hair the most (because there's a lot of talking in there), the windows were all closed. But that's a minor thing in the long run, as distracting as it is in the moment.
I definitely found myself getting frustrated with the game too when I played it earlier this year, but that was more at the combat than anything else. I was very bad at it. I did end up using a guide a couple times when I got stuck, and to find some hidden upgrade type things too. If it helps you enjoy this (great) game, then I think it's okay to use a guide. Just don't use it too much, and spoil the good parts!
