I strongly believe that cheating is anything a person does that is against the previous agreement with his/hers partner. Sex really has nothing to do with it. If a couple decides and agrees on being monogamist then sleeping with somebody else is cheating, and if they agree, strongly agree that they will not talk with their mouth open, if they do so, it is also considered cheating :)

I know couples that are not monogamist and have healthier relationships with so much more love and understanding. Sex is never the problem, the betrayal part of it is.

This was an interesting post to read, I found the statistical data funny, especially on music and hair colour :) Thank you for sharing this with us.
