What does it mean, if every time you are close to me

I get all nervous, 

I smile almost hysterically,

I only know how to look into the ground or into your eyes,

and when you take all the control and come closer

and you want to kiss me and that makes my organs shake inside?

Maybe it is easy to explain why all this...but I don't know...and I never felt all that...and no,  I will never confes it to you.
