I suppose that to each their own. What two consenting adults do in a loving relationship (preferably married) is their own business. If you want to watch graphic videos, play out fantasies or whatever, go for it as long as both agree and no one is hurt. Personally I would much rather be doing it myself rather than watching someone else in a video. Sex is God's creation and gift to be enjoyed. I do not see where my religious beliefs inhibit that in the slightest
