The Songs of Solomon are quite a strange little episode in the bible. Very clearly ancient love poems with what you can easily interpret as some references to sex. They are really rather beautiful (but what they are doing in the bible has never been satifactorily explained! I think the official line is that they are about the love of God but if you read them all, then they are very obviously simply love poems. Most people see them as a bit of a blip religious-wise, but of course the old testament is a collection of lots of ancient stories and ideas from the middle east, not all relating to Judaism/Christianity).

Beloved
2:3As the apple tree among the trees of the wood,
So is my beloved among the sons.
I sat down under his shadow with great delight,
His fruit was sweet to my taste.
2:4He brought me to the banquet hall.
His banner over me is love.
2:5Strengthen me with raisins,
Refresh me with apples;
For I am faint with love.
2:6His left hand is under my head.
His right hand embraces me.
or this one
6How beautiful and how pleasant are you,
Love, for delights!
7:7This, your stature, is like a palm tree,
Your breasts like its fruit.
7:8I said, "I will climb up into the palm tree.
I will take hold of its fruit."
Let your breasts be like clusters of the vine,
The smell of your breath like apples,
