Is it normal to want an open relationship

An open relationship is not a good idea if you're having problems with your significant other, that does not mean that people who desire open relationships should not have them if that is what both parties want.

In my relationship there is no such thing as cheating, we're open and very happy with our arrangement. We met, became friends, and eventually transitioned into a relationship which we discussed first. We don't feel that it is right to control your significant other, we don't see anything wrong with sharing. We have no jealousy issues and trust and care for each other very much. This is what works for us, this is what makes us happy. We are very much proponents of free (but safe ;P) love.

(despite the openess we have been together for 8 months without feeling the need to go elsewhere. Still trying to find another girl to come join our fun though XD)
