I am really, rather terribly attracted to a guy from work.. he too does give subtle hints... I am a mother of a 4 year old with an amazing sex life with my husband but my mind still wanders.. And I can't control it... Any reason why this is happening-I must add here that I am very happy with my married life yet feel like straying-Pls advise

yes its normal and happen even to most loyal and faithful spouses, but once you entertain/foster that curiosity, that's when it become a sin. dont do something you will regret in the end and never fall into someone's trap coz you will never know, when your dark secret gets revealed, its not just your husband you will lose, that guy might even take his back on you and you might lose your job out of shame. avoid or cut it immediately before you regret it.
