Fidelity

Hello, I am wondering how everybody here has been affected by ideas of relationships. In the Family there were swinging, threesomes and laws against adultery did not apply, almost anything went. Now many of us are in couples relationships. In some both are from the Family, and other couples only one person has been in the Family. Do we manage to remain faithful and do we have the same definition of "faithful" as the "system" people do? Do some of us cheat? If yes, do we justify it and make excuses? Of course many people in the "system" cheat too but they don't make excuses for it the same way. Did some of us suffer from bad relations because we could not remain faithful to one partner?
