Why do married men flirts a lot?

Really? I think that is a very subjective opinion of yours. I'am a married guy but I don't really flirt around. :)

i think that married me flirt alot because they marry someone sometimes because they feel that it is time for them to settle down and dont really want to be with the person. or their wife changes after they get married.

It's to find thrills. Actually the joy of relationship is most pleasant in the initial stage where both parties are so willing to humour the other as well as to put the other on a pedestal and let the other feel tops, excellent, etc. There is also the thrill of mysterious unknown and the thrill of hunting and predating. Flirting makes one feel alive again after being buried by the burdens of supporting and maintaining a family and marriage. Why single women? Simply cos they should be more willing, either more innocent(easy target) or more lonely. And if they are there for the taking(willing), why not.

For me I really don't know exactly why but I guess they just want to feel that they're still hot. Or they still look attractive to other women especially young women. It's probably guys ego.
