When Jove Meyer, a wedding and event planner in Brooklyn, is working with a same-sex couple, he sometimes finds himself cringing when he hears a guest use the term “gay wedding.”

“It’s not with bad intention, but people like to label things because it’s easier to discuss,” said Mr. Meyer, who runs Jove Meyer Events. “But the couple is not getting ‘gay’ married. They are getting married. They’re not having a ‘gay wedding.’ They’re having a wedding. You don’t go to a straight wedding and say, ‘I’m so happy to be at this straight wedding.’”

With the legalization of same-sex marriage in the United States in 2015, weddings among the L.G.B.T.Q. community have been on the rise. Nearly 3 percent of all weddings in the country are for a same-sex couple, according to the Wedding Report, a research company based in Tucson. So, when guests find themselves witnessing vows of a gay couple, it might be helpful to know that how they say something could offend the couple they so dearly love as they celebrate with them.

Mr. Meyer, who also advocates for the L.G.B.T.Q. community and identifies as a gay man, explained that labeling same-sex couples as different from any other wedding is the root of the cause. The qualifier to describe the wedding signals that it’s unlike a wedding of a heterosexual couple. It feels exclusive. While the party may have untraditional details, it’s a legal marriage like any between a man and a woman. A same-sex couple and a straight couple both say the required vows and sign the same marriage license to be recognized as legally wed.
