Celibacy can be a choice in life, or a condition imposed
by environmental encounters:

While attending a Marriage Encounter Weekend, Tom
and  his wife Thelma listened to the instructor declare,
"It is essential that husbands and wives know the things
that are important to each other."

He addressed the men.  "Can you name and describe
your wife's favorite flower?"

Tom leaned over, touched Thelma's arm gently and
whispered, "Pillsbury All Purpose, isn't it?"

And thus began Tom's life of celibacy...
