why some are interested to build an extramarital relationship?

extramarital relations preferred because without bond and demands commitment. In addition, extramarital relations, more convenient to run because if the relationship broke up, we go back to the real identity, do not worry about the cost of living children, do not have to think about the division of community property

when one person does not get satisfaction with there partner so thy need one so get satiated so they do it

how many are not having this? i guess almost everyone have extramarital relationship at some point of time
