That wall is not part of the original temple as not one stone stood on another when it was destroyed
"
As Jesus was leaving the temple, one of his disciples said to him, “Look, Teacher! What massive stones! What magnificent buildings!”
“Do you see all these great buildings?” replied Jesus. “Not one stone here will be left on another; every one will be thrown down.”

That wall might be fort Antonia
& the Jews are symbolically humping the wall
The Antonia Fortress (Aramaic: קצטרא דאנטוניה)[a] was a citadel built by Herod the Great and named for Herod's patron Mark Antony, as a fortress whose chief function was to protect the Second Temple. It was built in Jerusalem at the eastern end of the Second Wall, at the north-western corner of the Temple Mount.
The Baal Shem Tov, the 18th century founder of Hasidic Judaism, notes in his ethical testament, Tzavaat HaRivash, that the swaying in prayer is similar and connected to the act of copulation. He writes, "prayer is zivug (coupling) with the Shechinah. Just as there is motion at the beginning of coupling, so, too, one must move (sway) at the beginning of prayer. Thereafter one can stand still, without motion, attached to the
Shechinah with great deveikut."[12]
