Know (sexually)
This can, of course, be a wonderful thing: It is essential for our journey to heaven, and is the reason for the holiness of marriage. But when the men represent falsity it can also be horrendously twisted, as in the attempted homosexual rape in Sodom (Genesis 19) and the rape of the concubine in Gibeah (Judges 19). In a general sense, men represent things of the intellect -- facts, ideas, knowledge, everything from the deepest truths to the most pernicious falsities about life and the Lord. Women in general represents things of affection -- desire, passion, caring, everything from the most exalted love for the Lord to the darkest hatred. When a man “knows” a woman in the Bible, then, it represents a joining together of those intellectual and affectionate faculties. “Know" is also often used in connection with virginity. A women who has “not known a man” represents the affection for truth, unsullied by falsity.
Mark 1:23-29
23
And there was in their synagogue a man with an unclean spirit; and he cried out,
24
Saying, Let us alone; what have we to do with thee, thou Jesus of Nazareth? art thou come to destroy us? I know thee who thou art, the Holy One of God.
25
And Jesus rebuked him, saying, Hold thy peace, and come out of him.
26
And when the unclean spirit had torn him, and cried with a loud voice, he came out of him.
27
And they were all amazed, insomuch that they questioned among themselves, saying, What thing is this? what new doctrine is this? for with authority commandeth he even the unclean spirits, and they do obey him.
28
And immediately his fame spread abroad throughout all the region round about Galilee.
29
And forthwith, when they were come out of the synagogue, they entered into the house of Simon and Andrew, with James and John.
