Thou doth protest too much, methinks....

Often the traits that people attack others for are because they have the same trait and they are ashamed. I'm not saying you are guilty of cheating....but you must fear it.

It's why we can count on another "family values" politician being caught in an affair and another anti-LGBT politician being caught getting his dick sucked by another man (or vice versa).

People are people are people. Why do you feign surprise that less-than-honorable actions cut across all socio-economic, culture, religious/non-religious, educational, age, and political lines? It's not really any surprise. I'd be more surprised if it didn't.

That you have bought in the the concept of "Cheating" does not portend well for happiness with your future partners.

Quoting statistics is all good. But your derogatory concluding comments are a reflection of how little you understand the statistics, and obviously have done little other research.

You age reflects you lack of experience. You are yet to learn how relationships develop and change. But, it is possible you will learn nothing, given your current "thinking."

The older you get, the more you will see and experience. I would almost guess that by the end of life there will be few people who can admit to not having had a dalliance. I'm using that word rather than cheating because I think a lot of people have the knee jerk reaction to cheating as a harsh word. But may I add that as a woman I am as upset with emotional infidelity.

Monogamy is unnatural behavior. Most species do not mate for life.
Humans are the only species that can actively choose one way or the other.
It's unreasonable to expect fidelity simply as a matter of course. If you're doing that
with your partner, you're setting yourself up for disappointment.
Just don't promise to be faithful to a partner. If you know you like to engage with more
than just one person, do not promise that you won't.
If you do make that promise, then keep it. No excuses. If you cheat, you're a lying scumbag who can't be trusted, EVER.
It's not that hard.

"Why are we all faking?" What do you mean? It's only 16% who are cheating. That's hardly anything, really. How long do most marriages last? And for the record, I did not cheat on mine.

"Having sex with someone other than spouse while married" and "Cheating" are not necessarily the same thing, that's religion talking not actuality. Open marriages, swingers and polyamory to name a few are not cheating as long as everyone agrees to it.
As for the old not being wise considering the question was probably posed as "have you ever" of course their numbers are higher if you assume that they had the same rate of sex outside their marriages as 18-34 year olds in the next 30 years you only add 6% to that number. Add to that the fact that in the older age groups their is more likely to be one partner who is incapable or disinterested in sex and possibly quite happy for their partner to get it elsewhere and I'm surprised the numbers aren't higher.

Why is there not a category for religious or not?

Hey, take off points for the Republicans who can't help lying and the 65+ are just bragging so dock them a few points as well. As for the men/women numbers, figure more women would if they weren't stuck at home with the kids while their husband is out "cattin" around.

The average is 16%.... that is not even that much in my opinion lol. I expected it around 40-50%

Cheating and enjoying what you can't give her are 2 different things ??
