I am definitely a morning person, as the sun rises, so should I. Sex in the day for me has always been better. I just don't feel as excited in the evenings as I do in the day. Maybe because fatigue plays a big part. But its not to say that an afternoon nap wouldn't change this or sometimes having the right partner, who just energizes you, just the kind of CPR I like. There has been times I wished I signed a DNR.
