I don't know who you've been talking to - no one I know considers it immoral when done within a loving marriage. Out of wedlock is another story. I think sex is God's gift to us...and as such should be used appropriately...any other use is an abuse of it. I even have non-Christian friends who also agree that sex is God's (some sort of God) gift to us...

Sex on the other hand is considered by many to be dirty and immoral, and depictions of it are not widely accepted as appropriate even though the result of sex, children, are viewed by those same people as a blessing and a wonderful thing.
There seems to be some disparity between perceptions of sex and violence and the perceptions of their ultimate outcomes.
