Kindest Regards, Cage!
Just one more before I call it a night:
Maybe a sound definition of Lust is in order? I've always assumed that what Jesus meant by lust was a strong desire to be with a woman. ...So how do you avoid this kind of desire? It is utterly, and completely natural, and unless you're happily married, I see no way around adultery, as Jesus layed it out in Matthew 5.
I see a little bit of confusion with terms. Adultery is sex with a married person, to whom you are not married. I suspect you mean fornication. Forced to pick between them, I would rather fornicate than commit adultery, if that makes sense. Both parties must be single, "unattached," to fornicate. Fornication could be said to be a lesser offense (and herein enters the argument of whether such even exists, the old "a sin is a sin is a sin" argument, which I do not hold). I sense it to be lesser because number one: sex itself is not the sin. Number two: there is no intrusion into a sacred bond (an oath before G-d and witnesses to hold each other alone, forsaking all others, let no one come between them...). Number three: infidelity destroys families. Some sins are solo events, you do the damage to yourself. Some sins affect others too. Some sins can adversely affect how you get along with your family, nuclear and extended, and friends, possibly for the rest of your life.
Nobody cares if you smoke a little dope. Except the man, and that is so he can collect his share of the spoils and keep you in submission. But to (*G-d forbid, I do not in any way wish this*) rape your daughter will bring about repercussions for the rest of your life! That is a sin that might be forgiven, but you *will* pay for it, over and over and over. So yes, I do see greater and lesser sin. Fornication is a lesser sin, Adultery is a greater sin.
Lust is a bit more vague. I can see my understanding, which is admittedly vague even to me, is a bit different from those of you and China.
