How do i know its- real

I'm not a bit naïve
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.
