Claudaniel Fabien, 30, and Melody La Luz, 28, teach abstinence courses in schools and wanted to practice what they preach, reports the Chicago Sun-Times.
So they agreed not to even touch lips until the minister said: "You may now kiss the bride" at their wedding.
"It was surreal," said Mr Fabien of the big moment. "It was like, my other self came out and said, 'Look dude, you're kissing her!'"
His bride described the kiss as "magical". "It feels like such a gift," she said. "When you value a kiss, it becomes something of worth."
The couple met on their way to a mission trip in Uganda in 2006. Miss La Luz had taken a seven-year vow not to date until June 2007, and the two lived in different cities, she in Chicago and he in Tucson.
After the trip, they talked on the phone, visited, and became friends. A year ago, Mr Fabien got a job in Chicago, and the two began dating. He proposed last July, writing "WYMM" in sand on a Miami beach. (Chicago Sun-Times)
