Masturbation, what an ugly word. Yes, we guys do it a lot. But, I believe trying to make it into an extended experience is wrong. Just get it over with and avoid impure thoughts. I wouldn't spend a whole lot of time worrying about it, I am sure there are plenty of other 'sins' that you could be focused on. Pornography, on the other hand, is gross and sad - sex is beautiful, but should be private, showing the world your sex act demonstrates deep personal issues IMO, and watching and supporting these lost souls is also disturbing. There is nothing funny about Porn, guys like to joke about it, but the people involved in it are most likely hurting about their actions and want to get out.
