An elderly submarine sailor had been dating this elderly lady for 
some time.  Finally they decided it was time for marriage. 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 sub sailor decided 
it was time to broach the subject of their physical relationship. 
"How do you feel about sex?" he asked, rather carefully. "Well," 
she says, responding very carefully, "I'd have to say I would like 
it "Infrequently." 
 
The old sub sailor sat quietly for a moment. Then, looking over his 
glasses, looked her in the eye casually asking, "Was that one word 
or two words?"
