Well, it isn't a question, I think, of what I believe is meant by "the flesh," but what Paul meant by it. And as I pointed out, he seemed to think "the sin-nature" and "the flesh" were synonymous. In the passage from Galatians 5 he listed the "works of the flesh," which included things like sorcery, selfish ambition, and jealousy. But these are not merely abuses of physical appetites like you mention above, they are sins of attitude, sins of heart and mind.
I wonder, too, how a person from whom the sin-nature has been removed - as you claimed - could be induced to choose to follow the desires of the flesh. If I have no sin nature, the impulse to sin arising from that nature is gone.
But if I have no sin nature, why would I not be impervious to all sinful temptation? A deaf man is impervious to sound, as is a blind man to sight.
I read in Scripture that as a born-again child of God I am already crucified with Christ. (Ro. 6; Col. 3:3; Ga. 5:24). My crucifixion with Christ is a "done deal" the moment I am saved. So, why do you speak of "crucifying self"? Paul wrote to the believers in Colosse:
Colossians 3:3
3 For you died, and your life is hidden with Christ in God.
Paul seemed to think all saved people were "dead to sin and alive unto God through Jesus Christ" (Ro. 6:11) as a product of their conversion. Crucifying oneself seems, then, unnecessary (as well as impossible). Paul also explains in the verse from Galatians chapter 6 that you cited that the Christian has been crucified to the World through Christ. It is not something we must do for ourselves.
Galatians 6:14
14 But God forbid that I should boast except in the cross of our Lord Jesus Christ, by whom the world has been crucified to me, and I to the world.
Do you see why I find your comments puzzling? Paul says here that he has been crucified to the World by the work of Christ on the cross, not that he must crucify himself to the World.
But, Romans 7:22 make it quite clear that Paul is speaking as a regenerate man:
Romans 7:22
22 For I delight in the law of God according to the inward man.
An unregenerate man does not delight in the law of God. As Paul clearly declared:
Romans 8:7
7 Because the carnal mind is enmity against God; for it is not subject to the law of God, nor indeed can be.
And:
Ephesians 2:1-3
1 And you He made alive, who were dead in trespasses and sins,
2 in which you once walked according to the course of this world, according to the prince of the power of the air, the spirit who now works in the sons of disobedience,
3 among whom also we all once conducted ourselves in the lusts of our flesh, fulfilling the desires of the flesh and of the mind, and were by nature children of wrath, just as the others.
Paul here describes the nature of the unregenerate person, which does not (actually, cannot) entail "delighting in the law of God." It seems pretty plain to me, then, that in the latter part of Romans 7, Paul was speaking of a regenerate person who was struggling with a "law of sin in his members." And this is reinforced by how Paul describes being taken captive by sin in verse 23, rather than being a willing participant in it as an unregenerate person typically would be.
Selah.
