To the guy who wondered how lust is related to masturbation...Jesus said that if you look at a woman lustfully, then you have already taken her in your heart. What do you think you're thinking about while jerking it?
I've already studied this from various sources, and you really have to hear all sides of that interpretation to make a balanced judgement. For example, if you take 11 Samuel 11 as an example, King David lusted on a neighbour's wife before she brought him in to commit adultery with her. According to what Jesus said, David's sin started when he started looking at her and allowed thoughts to ruminate in his mind and heart before taking it to the next step.
But here's the deal, he already knew that lady was another person's wife, and where it started becoming a sin is when he seriously entertained thoughts of committing adultery with her. He also had plenty of wives and concubines and had no reason to pick on a poor guy's only one wife.
That's a specific example of focusing on one particular woman in a coherent fantasy with an intent of committing adultery. Other than this particular example in the Bible, I cant find anything else to illustrate what Jesus is saying to help me interpret it in a balanced manner.
You have to make an insane stretch of arguement to apply that to every woman anywhere where you don't know if she's married or not. Or in the case of porn pics, where you'll never meet these people in real life anyway, so it's a moot point. Maybe you are just admiring a woman's beauty, and you are appreciating a natural art form.
Again, lust is hard to define. In my case, since I've never been with a woman, I don't see how I can lust on a woman since I've never been there, and thus am incapable of forming a coherent thought of 'how would this girl feel like in comparison to that girl', or "I wonder how she would be like in bed, I'd like to try her out', etc.. and actually start acting on that. However, that is not related to masturbation at all, and thus I dont see the relationship of masturbation and lust.
