Early morning wood is my favorite time to indulge in my favorite past time, sex.  Rolling over and having his flag at full staff just gets me so turned on that know matter how tired I am or sleepy I may still be, I have to touch it and get it out!  Often times, I wake him up with a morning surprise.  We are talking late night and early morning arousal and why you are so wound up when you awake from your slumber.
