I follow a lot of swinger/lifestyle podcasters, bloggers, and event hosts on social media. Some of them have a solid opinion about the word “swinger.”
One person on Twitter who owns a swinger/lifestyle dating site wrote:

Our group is entirely in their 20’s and 30’s, and I hear the word swinger all the time. When a new couple registers for a party, they have to tell us a little bit about themselves. On the same day that the person on twitter wrote that declarative statement, I had two young couples refer to themselves as swingers when they registered. These are the screenshots from their registration forms.

It is true that people have different ways they wish to be labeled, but there is real evidence that the word “swinger” is far from outdated.

#1. Search Engine Data
If your swinger/lifestyle website ranks high on google for “lifestyle” but not “swinger” you’re blowing it. The google keyword data shows that virtually everyone (not an exaggeration) uses the term “swinger” when searching for parties and events. It’s many thousands to one. In fact, Google doesn’t show any results for people searching for “Chicago lifestyle party” whereas “Chicago swinger party” is a popular search phrase.

This is so obvious when you consider that the only people who know about the word “lifestyle,” as it refers to non-monogamy, are people already entrenched. If you have been non-monogamous long enough to refer to it as the “lifestyle,” you already know where all of the events and parties are.

#2. Young Swingers Week is the most successful takeover. Of all the swinger/lifestyle resorts (Hedonism, Desire, etc.), and all the groups holding takeovers, it’s safe to say that Young Swingers Week is the largest and most successful. They rent nearly all 260 rooms at Hedonism during their March event, and also hold large events in July and October of each year.

#3. Young Couples Party in Chicago refers to itself, quite proudly, as a “swinger party” and sells out nearly every event. We never play the silly game of “we’re the best” or “we’re the largest,” but our attendance is large and consistent. If we were offending the non-monogamous community with the word “swinger,” that wouldn’t be true.

I believe that people who are deeply ashamed of the word swinger are somewhat deeply ashamed of themselves. Someone once said to me on social media, “I don’t want to be associated with what someone thinks of when they think of ‘swingers.'”

I said, “People think that ‘swingers’ have a few drinks and sometimes have sex with each others partners, and that is exactly what we do.”
