Circadian rhythms of human copulation

Circadia has a post about a brief study on how patterns of human love-making change during the day. Unsurprisingly, the most common times are before going to sleep and after waking up.

Notably, the original paper uses the scientific term ‘nycthemeral’ (meaning daily). This must be one of the most lovely sounding words I’ve discovered in quite some time.

    It sound pretty intuitive to my-self, I don’t know for you, but every night and everymorning,I can feel my sexual circadian rythms knocing at my doors ! But I’m a man, maybe it’s different for women ?
