Sexual Activity

Researchers the world over have reported a positive link between sexual activity and life expectancy. A recent study determined the level of sexual activity of nearly one thousand men form a town in South Wales, and then followed their health outcomes over the next ten years. The life expectancy for the sexually active men—those reporting orgasms twice or more a week—was 50 percent greater than for the men who experienced orgasms less than once a month.

Sexual Fantasy

When college men and women duly recorded in a diary every sexual fantasy or sexy thought they had over the course of a day, men reported about seven daily, and women between four and five. But in other studies where college students answered a questionnaire asking them to recall the same information, the men estimated they had just one sexual fantasy per day, the women one per week.
