Sigrid,
I'm Christian, but wasn't always.
I agree with what smile has already said. I read a lot of different things, not just Christian writers.

I'm not happy with a lot of graphic violence and will not watch that. I'm just too sensitive.

I don't mind sex scenes in a novel or movie, if they are well written and, again, not overly graphic. My preference, is to have some things left to my imagination - which I think is highly creative enough on its own

If a writer is just throwing a bunch of sex and violence into a novel because they feel that is what is going to "sell" it and it has nothing to do with the story line, than to me it's just trashy writing.

A good writer will engage the reader's imagination into the story and does not need to spell everything out for them.

Maybe, I'm just old fashioned but I feel there's just way too much sex and violence in our movies and far too little good stories or plots....

BTW, these were my views before becoming a Christian and have nothing to do with religious preference so much as personal values.
