@Aaron Skidmore,
You won't tell your wife?
But you've done nothing wrong. It's not criminal is it?
What you've done is immoral, and I'm sure your wife would view it as cheating, as she probably doesn't have such a loose interpretation of the wedding vows.
There are people who argue that having sex with a prostitute doesn't count as cheating because there's no emotional attachment.
And such people, like you, go through all kinds of mental gymnastics to justify their behaviour.
