I wish I were a cliff

I wish I were a cliff
Rather than a gentle hill
That climbing up on top
Might be some kind of thrill.

I wish I were a sand dune
Rather than a verdant garden
That my undulations
Might your passion harden.

I wish I were a vixen
Rather than a faithful dog
That you might pursue me
With more than just a nod.

But I am the one I am
Rather than the one I'm not,
So please make me the fantasy
That keeps our loving hot.
