Ed Sheeran performs onstage during the 2015 Billboard Music Awards at MGM Grand Garden Arena on May 17, 2015 in Las Vegas, Nevada.

Ed Sheeran is great with his fans -- but one had a request that he just had to turn down.

Take it away, Ed:

"The fans are always really nice! Really polite and gracious. The parents are the ones that do the things that I think are odd," he told Entertainment Weekly in a recent interview. "There was a woman in San Francisco, she wanted me to be her daughter's first kiss -- and her daughter was 9.

She was like, 'Well, Carrie Underwood did it for this 11-year-old boy last week!' If Carrie Underwood kisses an 11-year-old boy, he goes into school the next day and they go, 'Oh, you absolute lad!' If a 9-year-old girl goes into school and goes, 'I got kissed by a 24-year-old yesterday,' police are being called, you know?"

That's probably a good policy in general.
