Can swinging hurt a relationship?
Yes — particularly for couples who enter the lifestyle to fix existing problems, who pressure a reluctant partner, or who fail to negotiate clear boundaries. Common failure modes are: one partner falling into "new relationship energy" with a play partner; jealousy that wasn't anticipated; one partner discovering they want monogamy after all; or imbalanced enjoyment where one partner consistently has more options. Lifestyle counselors recommend addressing existing relationship issues monogamously first, and entering the lifestyle from a position of strength rather than as a last-ditch fix.
