Many aspects of human sexuality are puzzling. Take celibacy, for example. This can be a choice in life, or a condition imposed by environmental factors.
While attending a Marriage Encounter Weekend, Tony and Julie 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 each name and describe your wife's favourite flower?"
Tony leaned over, touched Julie's arm gently and whispered, "Spiller's Self-raising, isn't it, luv?"
Thus began Tony's life of celibacy.
