I hope they are referring to a relationship of mutual consent.
Am I one of the few that finds much flirting to be distasteful. I'm referring mainlany to suggestive flirting in which the "flirter" is only teasing the "flirtee." There is nothing I dislike more than when a woman seems to come on to me by "flirting" and then if I respond with interest, she immediately turns off.
Now flirting between two people who understand the rules and one another can be a lot of fun... as can light hearted flirtation early on in getting to know someone.
Wow... I see Walter is here too.
