When a guys dick is starting to get hard, but only half way.
You are starting to get interested but not sure if you are all in.

She seems great at first and you would totally do her, until you get a better look, or talk to her for a while.
She was giving me a little chubby untill she turned to face me and I saw a mole on her cheek with a hair coming out of it.... then not so chubby.

Things can change in an instant.
