i have never done either. and i never will! i know you should never say never but i truely believe that. i come from a family that was broken up due to my mother's infidelity. i have seen what it does to families. i will never do that to my husband or children, and i will never do that to the children or wife of the "imaginary man" i would have an affair with. i think alot of people have affairs and don't really realize how many people their decision is effecting. its not just the 2 consenting adults. most times there are innocent kids involved. try having that on your conscience. so think about that b4 ever even considering taking part in a relationship like that. i mean there are like billions of the people in the world. why do u need someone elses man or woman?? ok....well i'm gonna get off my soap box now!
