One word or two?

An elderly couple had been dating for some time and decided it was
finally time to marry. Before the wedding, they had a long
conversation regarding how their marriage might work. They discussed
finances, living arrangements and so on.
Finally the old man decided it was time to broach the subject of their
physical relationship.
"How do you feel about sex?" he asked, rather hopefully.
"Well, I'd have to say I like it infrequently," she responded.
The old guy paused... then he asked, "Was that one word or two?"
