What is the easiest way for two married people to carry on a secret affair?

Answer 1

You don't - and if you both feel you need to you both should not be with your spouses or in committed relationships, get a divorce - then you can do whatever you want. Think of it this way how would you feel if your spouses were doing this behind your backs. Affairs never end good so be realistic about this and stop what does not and should not be started to begin with.
