So what are the arguments against masturbating? The main arguments I know are that
a) people often masturbate while watching porn or other sensual material, and that's obviously wrong.
b) that people have sinful thoughts while masturbating, and that's obviously wrong.
c) that it's impossible to masturbate while having sinful thoughts.
Now, I agree with a) and b) but not necessarily with c), maybe if you work on it and guard your thoughts it is possible to masturbate without having sinful thoughts. Maybe not for all people, but for some. People act like c) is a fact that doesn't need proof, but I'm not too sure of it, surely your first instinct is to think about sexual stuff while you masturbate, but if you know that that's sinful and take care not to do it, it might be possible to do it without having sinful thoughts.
Now suppose you don't watch porn and can stop yourself from having sinful thoughts, what else would be against it? Is there some other argument to disallow it? Maybe you could tell me, because I don't see it, and as I said the Bible nowhere explicitly forbids it.
And I agree, every addiction is bad. But what I meant it that you can get addicted to anything, unless you're prone to addiction that's not really a reason not to do something, or else we all wouldn't be drinking alcohol, playing video games, eating junk food from time to time, etc. All stuff we could also get addicted to.
I don't have "proof," per se, for c), but I really don't see how it's possible for it to be not true. What would be the purpose of masturbation, then? Relieve stress? Maybe. But if it causes you to be tempted by sexual thoughts (which it invariably would, in my opinion), then why do it? Why put yourself in that situation? Is it even worth trying to get to a point where you can do it without lusting? I don't think so.
Ah, okay. I guess I was just confused why you put that there, because I'm not sure I was making a case that it was bad simply because you could become addicted to it. Looking back at my comment, I guess it did seem like that's what I was saying; sorry for being confusing, that's not what I meant.
It just comes down to this for me: I cannot say whether or not the specific ACTION is sinful, but I DO believe that it cannot be done without sinning. Does that make any sense?
