What means "lies"?

Those are the words to popular songs and they aren't intended to have any sort of deep meaning. Lies = untruths. It's not a metaphor for body parts.

However, understand that the Hosier song, Take Me to Church ("I'll worship like a dog at the shrine of your lies".) is about a homosexual relationship. He's not talking about worshiping; he is talking about sex.

It is possible (I have no idea) that this song uses this definition:

NOUN
(usually the lie)
1 The way, direction, or position in which something lies.
'he was familiarizing himself with the lie of the streets'


Which is based somewhat on this definition:

VERB

3 [no object, with adverbial] (of a place) be situated in a specified position or direction.
'Kexby lies about five miles due east of York'
