Where in the Psalms does David write about the Lord with sexual innuendos that were common IN HIS DAY? I don't believe for a minute King David was using sexual innuendos or references that were common in his day to speak of his worship to the Lord. His worship was full of reverence, honor, and respect for the Mighty God. No Psalms comes to mind where David said "I want to touch your face, hear your heart beat, and caress you with songs of love" etc. etc.
No, his Psalms spoke of the majesty, honor, and glory of God, of his kingship... I suppose you could be able to dig up a reference in the Psalms that may have some sexual innuendo to it... but a thousand more references to the kingship, honor, glory, majesty, strength etc. of the Lord.
Psalms 24: 6-10
6 This is the generation of them that seek him, that seek thy face, O Jacob. Selah.
7 Lift up your heads, O ye gates; and be ye lift up, ye everlasting doors; and the King of glory shall come in.
8 Who is this King of glory? The LORD strong and mighty, the LORD mighty in battle.
9 Lift up your heads, O ye gates; even lift them up, ye everlasting doors; and the King of glory shall come in.
10 Who is this King of glory? The LORD of hosts, he is the King of glory. Selah.
