Oxytocin

I read this thing in a magazine that said when a girl has an orgasm it releases an oxytocin in the brain
The oxytocin that stimulates the part of women's affection and attachment
So maybe if I'd been a bit more selfish in bed you wouldn't have to confuse me now

And I heard this story about when you were on holiday last year
You got drunk and started talking about me
The things you said

I know I said I'd never do it
I thought I couldn't do it
I think I need a friend
