I don't see the big deal. If you're just looking at porn, it's just mental stimulation. Is the argument that you will be desensitized because of it?....that seeing all of this stuff will make the sex you have in real life seem to blah? If so, it doesn't work that way for me. Porn is like walking by a restaurant and smelling the delicious aroma from their kitchen. It just makes me want it more. And when it comes to sex, the actual feelings of contact are way better than porn and I and my body seem to know it. I'm definitely not any less interested in sex because I've watched porn.
