The old grey mare ain’t what she used to be

From NRO’s Corner: The San Francisco Chronicle asked Walter Cronkite to what he attributed the longevity of his own marriage to Betsy: “I do think one of the factors was we were of different sexes.” He looked delighted as the laughter billowed around the room. “That doesn’t mean I wouldn’t have been happy to be married to several friends I had of the same sex,” he followed. “It just never came up in our particular relations.”

Did Walter mean to imply that he was interested in having sex with these friends? I’m not sure that the senile old globalist understood why the room was laughing.
