The classical comment would be, "I don't understand, how can nudity bother you while violence doesn't?"
I kinda stopped trying to understand a while ago. Violence is an act of hatred or fear while nudity is.. well, natural. We are all naked individual wearing clothes. The cynical could tell that violence is also a very natural human trait, but I guess you got my point. It's all a question of education, I guess. After all, there are people teaching their child how to hold a gun but not telling them how babies are conceived. *shrug*
On the other hand, nudity also kinda prevented me from playing the Witcher games, especially the first. Well there wasn't really nudity in TW1, but they sold their game claiming it was a "dark and mature game", and for some reasons, people tend to think that 'mature' means including sex/nudity. The amount of girls Geralt could frak ( and, worse, keep trophies out of those encounters ) was stupid. So you see, it's not nudity itself that bothered me, rather the gratuitous use that was made of it...
