[Midway Monster]

A married coworker of mine has done a few things and I am curious if they would be considered cheating.

1. Shown me her panties (just the very top quickly and briefly)
2. Talks in flirty sexual inneundos
3. Tells me what color panties/bra she has on occassionally (usually in a joking manner)
4. Talks about her sex life (but not in very much detail)

I have been married for 6 years and I know this stuff is not right. I would never want my wife to know about it. People always say if you would not want your significant other seeing or doing what your doing it is wrong. I get that. But I am just curious if it would be considered cheating or even having an affair. This woman loves to flirt. Some people I think are just flirts by nature. If it was not with me it would probably would be with someone else. I have no intentions of cheating but do have to admit being flirted with like this makes me feel good. That is why I am curious if two people just flirting with each other like this and leaving it there is a bad thing. Is it considered cheating on your spouse? Very perplexing?
