"I can't fly a flag for monogamy or whatever the opposite is; it depends on the person and on the situation"

This quote by Sting recommends that he does not think in having a single set of rules for relationships. He believes that everyone and circumstance is unique and need to be treated as such. He does not think in having a blanket rule for all relationships, such as monogamy or its opposite. Instead, he believes that each relationship needs to be assessed by itself benefits which the best strategy need to be figured out based on the private circumstances. This quote shows Sting's belief that relationships should be treated with respect which each person must be enabled to make their own choices about what works best for them. He is not advocating for any specific type of relationship, but rather for the flexibility to choose what works best for each individual.
