What seems silly to me is when people believe that this spiritually fallen physical realm is what God intended...
If one describes the physical world as "spiritually fallen", one can only conclude that this was clearly not the will of God. God created everything and declared it "good", even "very good".
But it is precisely that "good", that "very good" world which God created "physical": stars, planets, skies, earth, waters, fish, birds, beasts, and yes, humans with genitals.
...that our physiology is meant to function in a non-deified state.
14 And when the hour came, he sat at table, and the apostles with him. 15 And he said to them, “I have earnestly desired to eat this passover with you before I suffer; 16 for I tell you I shall not eat it until it is fulfilled in the kingdom of God.” 17 And he took a cup, and when he had given thanks he said, “Take this, and divide it among yourselves; 18 for I tell you that from now on I shall not drink of the fruit of the vine until the kingdom of God comes.”
36 As they were saying this, Jesus himself stood among them. 37 But they were startled and frightened, and supposed that they saw a spirit. 38 And he said to them, “Why are you troubled, and why do questionings rise in your hearts? 39 See my hands and my feet, that it is I myself; handle me, and see; for a spirit has not flesh and bones as you see that I have.” 41 And while they still disbelieved for joy, and wondered, he said to them, “Have you anything here to eat?” 42 They gave him a piece of broiled fish, 43 and he took it and ate before them.
Yet, we believe that humanity and the universe was meant to function in direct communion with God through His Grace/Uncreated energies which are separate from creation. In other words, it's not just that our actions have become subject to evil through the fall, but that we lost our real ontology; without God's Grace, deification, man is not what he is meant to be. It's not very helpful to speculate how our organs would function in a deified state because we know that first and foremost we need God to personally restore us to that state and give us His own knowledge about Himself and us. So, firstly, we are required to repent and live an entirely new life in Christ as He taught and then we can talk about how stuff really works.
While affirming that it's not helpful to speculate on the deified state of human physiology, people who think/believe in this way go toward another extreme: they feel free to speculate on just how fallen human physiology is, seeking to separate it from God's creation. Why make our problem God's problem?
Even after humanity suffered the Fall, God did not declare the things and people he made "bad" or "very bad", undoing his declarations in Gn 1. Sickness and death entered the world through sin, but they do not change the fundamental goodness of man as God created him, because he is created, male and female, in the image and likeness of God (i.e., Christ). Not only do we come to understand what "image" and "likeness" mean in light of Christ, but we also understand what "male" and "female" (i.e., sexes, with all their physical, mental, emotional, psychological, spiritual differences and complementarities) mean through him.
I can agree with everything you said about the need for repentance, divine grace, etc., but I cannot agree with the spiritualising tendency that strips humanity of humanity in order to become like God. It's anti-incarnational and a form of spiritual fornication.
