When Benjamin Glaze, at the time a 19-year-old cashier from Enid, Okla., auditioned for “American Idol,” he had hoped his big moment would come as he belted out “Stadium,” a song he wrote himself. That or Nick Jonas’s 2015 single “Levels.”

Instead, it came when the pop star Katy Perry, a judge on the show, surprised him by kissing him smack on the lips, moments before his audition. He had never been kissed before.

“I was a tad bit uncomfortable,” Mr. Glaze said by phone this week, after the incident aired on the season premiere. His first kiss was a rite of passage he had been putting off with consideration. “I wanted to save it for my first relationship,” he said. “I wanted it to be special.”

“Would I have done it if she said, ‘Would you kiss me?’ No, I would have said no,” he said. “I know a lot of guys would be like, ‘Heck yeah!’ But for me, I was raised in a conservative family and I was uncomfortable immediately. I wanted my first kiss to be special.”
