I believe that a number of people are exploring non-monogamous relationships because they want to "explore" the desire that they feel for others.

It is natural to feel sexual desire, or desire an intimate friendship with someone other than your spouse.

In this time it is becoming a bit more acceptable to explore, so more people are allowing themselves to do so.

It is certainly not a move to just be trendy. Now, in some situations, women act bi when others are around for attention, but that is the only actions that appear due to trends.
