Understanding Satans world prt 6 (demon and giant origins)

1 Enoch cp 3:7 And all the others together with them took unto themselves wives, and each chose for himself one, and they began to go in unto them and to defile themselves with them.
Notice how it says Angels defiled themselves with women. This means they regretted it. They are Angels. You see for an Angel to marry a woman means it is two seperate species marrying each other. So the women and the Angels probably felt strange marrying each other. Human men and women are meant to marry each other. Because men and women are the same species. Angels are not human. The women possibly found it strange marrying a different species from themselves. I don't know how they felt. When you marry the correct species as yourself with love, it is not defilement.
