Titbit: Sex on the Brain
Apparently the average 18 to 30 year old male thinks about sex somewhere between once every 52 seconds and once every two minutes; depending which research you believe. Sure there are times when he might go for up to half an hour without thinking about sex but then he more than makes up for it in order to catch up to his average.
Sadly the average 18 to 30 year old female only thinks of sex about once a day.
