That verse has nothing to do with masturbation. That has to do with eliminating our sinful natures. The Bible never mentions it at all nor implies anything about it, nor makes any statement about the act itself, therefore it is not sinful and therefore has nothing to do with the flesh.
Masturbation has nothing to do with the
crucified flesh. And you don't believe that Christ sanctified the flesh? That's nothing new of course: in fact such gnostic heresies are mentioned many times in the New Testament. Those who claimed at Paul's reception in the Areopag to have no need for the resurrection make up one example. Others are found in the letters. The flesh cannot be put in a simplified category and be labelled sinful just like that, especially not when when it's the crucified flesh, and not just any flesh. Crucified flesh does not equal "eliminated" flesh, but flesh that Jesus brought before the Father to have it sanctified.
Stick to your "inductive" approach, call me out for nitpicking, "semantics", ask for more verses or patronize me saying that I shouldn't quote them - I'm sure you thought of everything.

An inductive approach might work fine with some books, but it comes off as a little bit obsolete with the Scripture.
N.b. I'm not the one who's arguing that Scripture is either clear as desinfection or completely unintelligible, and nor was it deductive what I said. But it was based on the assumption that in the Scripture God gave us something more than what cold reason could fathom. From my side of the matter, there are a lot of things that I did not mention. I did not resort to simplified "masturbation-isn't-mentioned" arguments that one can safely stand by with a simple search engine, without having to read the Scripture at all. I'm not a rationalist, and I don't believe, as some do, that God gave us a Holy Scripture which is to be treated as the retail catalogue. Neither do I think that it's a catalogue of sins, by the way: no, in fact I made that clear in my first post and it was you, Jaws13, who said that masturbation can't be a sin since it isn't mentioned, and who had to accuse me of doing something wrong with the Scripture.
I had not planned to make more than one post in this thread, but a few random accusations lured me back in. And it's always nice to revisit a beautiful passage in the Scripture, to dwell on God's wonderous works.
