I myself am a sag and I never thought I would be able to commit and engage in a mongomous relationship...Lo and behold not only am I fully committed but my fiance is a Sag himself who has commiteed to our monogomus relationship. Prior to meeting each other we each thought that monogamy and marriage would never happen, at least to us. However after a few dates we both knew something was different, special. We are both free spirits who enjoy adventure and travel. And we are both extremely clear about the commitment we have made to be with eachother. So yes monogamy is possible but as a Sag we do not settle.
