For the most part, sin is gender neutral. Just as many men are willing to admit to their shortcomings as women. Nor is household income, education or race a meaningful barometer. Age, on the other hand, is the primary indicator of "sinfulness." Nearly half (41 percent) of Americans between the ages of 18 and 29 admit to committing four or more of the seven deadly sins -- three times as many as their parents' generation. One wonders if this is the result of a different kind of upbringing or if age brings a kind of moderation that cools the various passions. Or perhaps older people are just big fat liars.

Still, some lines are starkly drawn. Consider adultery. Do most people find it acceptable to take a little break from routine and have a quickie with someone other than their spouse? The answer is an emphatic no. When offered the opportunity to participate in sex outside an exclusive relationship, with the guarantee they would never be caught, only one in five Americans say they would "probably" or "definitely" consider taking the chance to see if the grass really is greener on the other side of the fence.

But here's where politics and adultery get interesting. The 2008 presidential matchup everyone is praying for pits current New York senator Hillary Clinton against former New York City mayor Rudolph Giuliani. Both candidates have faced issues of infidelity in their marriages, and both are aggressively seeking the support of active churchgoers who publicly reject that sort of behavior. When offered the chance to participate in an extramarital affair, with the same guarantee of not being found out, Clinton supporters are more averse to the idea. More than two thirds (70 percent) say they would probably or definitely not break their vows. By comparison, only 56 percent of the supporters of the thrice-married Giuliani feel that way.

Speaking of infidelity -- or rather, speaking of speaking of infidelity -- Bill Clinton certainly offered a memorable contribution to The Big Book of Immortal Presidential Quotations when he said, "I did not have sexual relations with that woman." After all the political hearings and attempted apologies, the phrase may be undying, but America would definitely not agree with its assertion. Clinton's defiant finger-wagging denial aside, an overwhelming 84 percent of Americans believe oral sex is sex. Even 81 percent of those voters who support Hillary Clinton -- and who may be thought to have supported Bill Clinton during his tribulations -- believe oral sex is sex. In fact, the only segment of respondents who even remotely believes otherwise is younger voters. A third of them (34 percent) think oral sex is more like necking or petting than intercourse.

Sure, there are some partisan sexual differences. Though both parties say they consider brains to be more of a turn-on than brawn (or breasts), Democrats are more likely than Republicans to be turned on by wealth (maybe because they don't have it). Republicans attend church more often than Democrats, but they also have sex more often.
