Let me add something else. When I write my fanfic, or other stories that I've written, I include violence. I'll have people splitting skulls, and cutting people open, and some pretty graphic things. I've also written things where sex is involved and implied and even nudity.
Violence in stories is a bit different from violence in a video game. Seeing violence in a very graphic and horrific way immediately puts that image imprinted into your mind. Describing it in a book doesn't quite have the same effect of imprinting it into your mind in the same way. When I have sex or nudity in a story, I try to avoid being very descriptive so that I am not enticing people with descriptions about such things. I tried to keep it as tame as possible because you never know what conscience is involved in the reading. I don't want to be the reason why somebody gets all worked up over something and then goes out and tries to reenact it with somebody who's not willing to fulfill that fantasy. I've known people who have problems with sex and controlling themselves. So I don't want to be a problem for those kind of people, and I don't really like things that can be a problem for those people.
I myself am not affected as much by such things. My parents used to take me to a nudist camp every weekend from the time I was 10 to the time I was 17 when I chose to stop going on my own. I've seen all the boobs and butts that I ever would ever want to see in my lifetime.
And I'll tell you now how I felt both then and now. Seeing naked bodies is uncomfortable to me. To me, it should be a special thing between lovers. I want my wife to know that she's All I ever need. I don't need to see naked pixel models. I don't need to see naked pictures of anybody. She's special to me, and I'm special to her. And how do I show her that she's special? One of the ways is that I don't go around staring at other women and admiring their bodies.
That's not something that I have to worry about with violence. Even if a video game is super violent, and I put up with it, it's not like I'm taking what is special between me and my wife and throwing it out the window. So there's a difference between accepting a game being violent and accept a game with nudity and sex flaunted all over the place.
