Are pineapple flags a sign for swingers?

There is no evidence that pineapple flags are universally recognized as a symbol for swinging or consensual non-monogamy. The association between pineapple flags and swinging is limited to certain communities and contexts, and its usage might vary across different regions and groups of people.

It's important to note that individuals interested in swinging or non-monogamous relationships usually communicate their intentions and preferences through personal conversations or established platforms, rather than relying solely on symbols like pineapple flags. Always engage in open and honest communication with your potential partners regarding your interests and boundaries.
