Heart in my mouth, the 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, I'm 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've got the power, it amazes me still
How you play my emotions with consonant 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 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

(Bite my shoulder, I might touch you and seize you and make you) 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 (to fade)
