this question become something that thought funny in our mind.
or something boring for some people who don't have a good moment in their marriage.
for me, having a couple in my life that can support each other it's really great.
everything become easier and of course more happy.
problem can solve easily.
but it depends on the decision both of the couple.
having contact with other woman or man of course less.
because we try to keep our heart and our  couple feeling.
