What's this?

I can't say no to you,
Just a splurge of energy.
Shouldn't let you touch on me so sweetly,
But I can't help that you come out of the blue.

This is new to me,
Something racing to my core.
Nothing felt like this before,
Don't wanna keep it in secrecy.

From my toes,
To the top.
I don't want it to stop,
I can feel it in my nose.

It's new for I,
But same old for you.
You don't try to hide it too,
I feel as though I could fly.
