Kelsey claimed that he had been chaste for a long time before meeting his new wife Kayte Walsh.
When addressing speculation that he and Walsh slept together on the night they met, he told talk show host Conan O'Brien: "Well we kissed that night. We didn't do anything much more than kiss for several months.
"I just wanted to clear that up... she was worth the wait."
When O'Brien commented: "I would think that would be difficult," Kelsey replied: "Well, for a guy that hadn't had sex for a decade it wasn't that hard!"
