Time to get hitched

[$parechange]

An elderly couple, who were both widowed, had been going out with each other for a long time. Urged on by their friends, they decided it was finally time to get married.
Before the wedding, they went out to dinner and had a long conversation regarding how their marriage might work.
They discussed finances, living arrangements and so on.
Finally, the old gentleman decided it was time to broach the subject of their physical relationship.
'How do you feel about sex?' he asked, rather tentatively.
'I would like it infrequently' she replied.
The old gentleman sat quietly for a moment, adjusted his glasses, leaned over towards her and whispered -
'Is that one word or two?'
