OK, After reviewing other posts, I see the following as acceptable:
Flirting with no intention if its a friend on yours and nothing sexual.
I find the following classed as cheating or unacceptable:
Flirting with a complete stranger, espcially when drunk as you have no need to flirt with a complete stranger unless you want something, mainly a snog or something more, and I also consider cheating to be anything from a Kiss to more.
Thats my views after reading some of the posts.
Fair enough ALL women flirt whether they say they do or don't. My wife says she never flirts, but I know she does, she says she doesn't to stop an arguement, but flirting with a complete stranger when out is just unacceptable for me as I wouldn't flirt with a women I didn't know as it is leading on if she classes it as 'just a bit of fun'
I respect a person more for being honest and no lying about it, lying about it just makes me think there was something more to it as why lie if it was harmless...?
Also, it would depend on the other person's past relationship history. For example, if you were with someone and the person your with cheated on their other half in the past or flirted sexually while with their ex, could they really change?
