You are absolutely correct Denadii. I might also add that those in the resurrection become like the holy angels in heaven, which neither marry nor are given in marriage. Fallen angels are a different story. I truly believe that the angels that are spoken of in 2 Pet.2:4 and Jude 6 who were put in chains of darkness in Tartartus until the great white throne judgment, are those angels who took wives.
"Now it came about, when men began to multiply on the face of the land, and daughters were born to them, that the sons of God saw that the daughters of men were beautiful; and they took wives for themselves, whomever they chose."
"The Nephilim were on the earth in those days, and also afterward, when the sons of God came in to the daughters of men, and they bore children to them. Those were the mighty men who were of old, men of renown."
In the scriptures above, there is a distinction made between mankind and the sons of God, ergo, the sons of god are not of the same genre as mankind.
Below is Enoch's version of Genesis 6:1
"It happened after the sons of men had multiplied in those days, that daughters were born to them, elegant and beautiful. And when the angels, the sons of heaven, beheld them, they became enamored of them, saying to each other: Come, let us select for ourselves wives from the progeny of men, and let us beget children. - Enoch 7:1-2
Below is the International Standard version translation:"Now after the population of human beings had increased throughout the earth, and daughters had been born to them, some divine beings noticed how attractive human women were, so they took wives for themselves from a selection that pleased them."
Below is Enoch's account of Genesis 6:1-4 in detail:
===============================================
It happened after the sons of men had multiplied in those days, that daughters were born to them, elegant and beautiful. And when the angels, the sons of heaven, beheld them, they became enamored of them, saying to each other: Come, let us select for ourselves wives from the progeny of men, and let us beget children.
Then their lead Samyaza said to them; I fear that you may perhaps be indisposed to the performance of this enterprise; and that I alone shall suffer for grievous a crime. But they all answered him and said: We all swear; and bind ourselves by mutual execrations, that we will not change our intention, but execute our projected undertaking.
Then they all swore all together, and all bound themselves by mutual execrations. Their whole number was two hundred, who descended upon Ardis, which is the top of mount Armon. That mountain, therefore, they called Armon, because they had sworn upon it, a nd bound themselves by mutual execrations.
These are the names of their chiefs: Samyaza, who was their leader, Urakabarameel, Akibeel, Tamiel, Ramuel, Danel, Azkeel, Sarakuyal, Asael, Armers, Batraal, Annane, Zavebe, Samsaveel, Ertael, Turel, Yomyael, Arazyal. These were the prefects of the two hundred angels, and the remainder were all with them.
Then they took wives, each choosing for himself; whom they began to approach, and with whom they cohabited; teaching them sorcery, incantation and the dividing of roots and trees:
And they conceiving brought forth giants; whose stature was each three hundred cubits. These devoured all which the labor of men produced; until it became impossible to feed them; when they turned themselves against men, in order to devour them; and began to injure birds, beast, reptiles and fishes, to eat their flesh one after another, and to drink their blood.
Then the earth reproved the unrighteousness.
Moreover Azazyel taught men to make swords, knives, shields, breastplates, made them see that which was behind them and the workmanship of bracelets and ornaments, the use of paint, the beautifying of the eyebrows, the use of stones of every valuable and select kind, and of all sorts of dyes, so that the world became altered. Impiety increased; fornication multiplied; and the transgressed and corrupted all their ways.
Amazarak taught all the sorcerers, and dividers of roots; Armers taught the solution of sorcery; Barkayal taught the observers of the stars; Akibeel taught signs; Tamiel taught astronomy; and Asaredel taught the motion of the moon. And men, being destroyed, cried out; and their voice reached to heaven.
Then Michael and Gabriel, Raphael, Suryal and Uriel, looked down from heaven and saw the quantity of blood which was shed on the earth, and all the iniquity which was done upon it, and said one to another: It is the voice of their cries; The earth deprived of her children has cried even to the gates of heaven.

God's response to what the angels had done by taking wives and all that they taught:
===================================================
Then the Most High, the Great and Holy One spoke; And sent Arsayalalyur to the son of Lamech (Noah), Saying: Say to him in my name; Conceal thyself. Then explain to him the consummation which is about to take place; for all the earth shall perish; the waters of a deluge shall come over the whole earth, and all things which are in it shall be destroyed. And now teach him how he may escape, and how his seed may remain in all the earth.
Again the Lord said to Raphael: Bind Azazyel hand and foot; cast him into darkness; and opening the desert which is in Dudael, (Tartartus) cast him in there. Throw upon him hurled and pointed stones; covering him with darkness; There shall he remain forever; cover his face, that he may not see the light. And in the great day of judgment (Rev.20:10, Matt.25:41)
Restore the earth, which the angels have corrupted; and announce life to it, that I may revive it.
All the sons of men shall not perish in consequence of every secret, by which the Watchers have destroyed, and which they have taught their offspring.
All the earth has been corrupted by the teaching of the work of Azazyel. To him therefore ascribe the whole crime.
To Gabriel also the Lord said: Go to the biters, to the reprobates, to the children of fornication; and destroy the children of fornication; the offspring of the Watchers, from among men; bring them forth, and send them one against another. Let them perish by mutual slaughter; for length of days shall not be theirs.
They shall all entreat thee, but their fathers shall not obtain their wishes respecting them; for they shall hope for eternal life, and that they may live, each of them, five hundred years.
To Michael likewise the Lord said: Go and announce his crime to Samyaza, and to the others who are with him, who have been associated with women, that they might be polluted with all their impurity. And when all their sons shall be slain, when they shall see the perdition of their beloved, bind them for seventy generations underneath the earth (2 Pet.2:4, Jude 6), even to the day of judgment, and of consummation , until the judgment, the effect of which will last forever, be completed.
======================================================
This was just a little excerpt form Enoch regarding the sons of God, those angels who took wives from the progeny of mankind and all that they taught and thereby corrupting mankind, which was the main reason for the flood. These angels, the sons of God, are also who 2 Pet.2:4 and Jude 6 is referring to.
