@stevenya,
Pornography is reality as a toys or a way to relieve yourself or even some couples might get turn on by watching pornography together. A lot of people thing of porn as a bad thing, and they are in part right and wrong. I try to compare it to alcohol. alcohol kills many life every year but also give a good time to many other, yet alcohol is not a taboo subject at all! Porn on is like alcohol cuz it's a stimulus that gives pleasure but nobody gets kill by it. You get to see fantasies you would not be able to see otherwise, but be careful that it does not take over and make you believe that sex will be like the porn you see. It can give erotic idea to a couples or great satisfaction to a single man or women, but also raise the expectation from your partner. Draw a line that put porn as a toys like sexy lingerie and your sex life as the real "reality".
