Heart in my mouth, pulse in my head
Mercury rising into the red
The smell of your skin can light up all the fires in me
Hungry to touch, eager to please
Out of control and I hand you the keys
Every night, I am burning to make love to you
But don't try to tell me you think it's all physical
It goes much deeper than that
You ought to know
It's an affair of the heart
It's an affair of the heart
It's an affair of the heart
Have a little blind faith, believe
It's an affair of the heart
When we make love it's a passionate thing
You shudder and shake sink your teeth in my skin
I almost believe you were made to be played by my hands
And you got the power it amazes me still
How you play my emotions with consummate skill
I don't have to look any further than into your eyes
So don't try to tell me you think it's just physical
It goes way deeper than that
You better to know
It's an affair of the heart
It's an affair of the heart
It's an affair of the heart
Have a little blind faith, believe
It's an affair of the heart
(I'm the controller)
(And I want to touch you and seize you)
(And make you mine) hey, hey
Don't try to tell me you think it's all physical
It goes much deeper than that
You ought to know
It's an affair of the heart
It's an affair of the heart
It's an affair of the heart
It's an affair of the heart
You better know, it's an affair of the heart
It's an affair of the heart
You better know, it's an affair of the heart
It's an affair of the heart
Baby, an affair of the heart
It's an affair of the heart
It's an affair of the heart
It's an affair of the heart
No, it's an affair of the heart
