I have sexual behavior statistics from the General Social Survery (GSS).

• Married people have more sex than unmarried people.
• People who work more than 60 hours a week are about 10 percent more sexuall active than other workers.
• Americans who attend Grad school are the least sexually active out of the college student group.
• Catholics are slighty more sexually active than Protestants. Jews and agnostics are 20 percent more sexually active than either.
• Sexual activity is higher among self-described liberals than among moderates or conservatives, and it is highest among those who describe themselves as "extreme liberals" and "extreme conservatives."
• People who own guns have higher-than-average sexual frequency.
• Sexual frequency increases among those who engage in other pleasurable pursuits, such as attending concerts, sporting events, and active forms of leisure. It also increases along with television viewing. The more TV individuals watch, the more often they have sex. "It is not clear," the researchers observe, "whether the sexual response is stimulated by what is on screen, or by boredom. And for some reason, watching PBS seems more positively related with increased sexual behavior than watching regular prime-time drama."
