Cover art for We Hunger lyrics by Siouxsie and the Banshees

I also think this is most likely about pregnancy and lust. She asks, do you hunger for this, in relation to the strech-marks, and uses the metaphor of the baby inside being like a parasite.

However, she also seems to be asking if we hunger for "The bliss of a sweet kiss."

The song seems to be questioning perhaps, the motives behind sex and if it is really all about children or about lust. Kind of like a cautionary tale for young people getting pregnant.
