How Do I Know It's Real

I'm not a bit nave
I know a kiss from a kiss
I know which thrills to believe,
I can't be fooled about this

How do I know it's real?
There's something within me feels it,
The beat of my heart reveals it,
And that's how I know.
How do I know it's real?
The way that your eyes caress me,
The way that your arms possess me,
And that's how I know
Whenever you are near,
My temp'rature ascends,
It all becomes so clear,
My doubt about it ends.
How do I know it's real?
I've known of it since it beckoned,
I think of you ev'ry second darling,
That's how I know.
