Hmmm. As a woman, and one who is definitely not a morning person, I can't say I understand the whole waking up and raring to go concept. I guess if I ever spent the night with a guy again and they were being an eager beaver first thing in the AM, I'd suggest a self pleasuring session (I know it's not the same, sorry) and roll back over to wake up at my leisure.
We ladies need a few minutes to warm the old engine up. Its not like cars these days where you push the button and go on your merry way.
