SEX CAN NEVER BE, UNLESS, Flesh of man die, for the spirit of woman(sex) to live in his flesh from life of his flesh until death.
God didn’t create but one flesh, that flesh is man, male and female.
God said to the flesh of man in the Garden of Eden. GENESIS 2:16 “From every tree in the Garden you may eat but from the tree having knowledge of good and evil thou shall not eat of it; for in the day that thou eat thereof thou shall surely die.
The Day the flesh of man ate the fruit, the spirit of woman(sex) became flesh of man, causing the flesh of every human body to die, for the spirit of woman(sex) to live in their flesh from life of their flesh until death. Jesus is the only way, the spirit of God can live in the flesh, without the spirit of God in the flesh, the flesh will surely die.
