There are three possible parts to a date, of which at least two must be offered:  entertainment, food, and affection.  It is customary to begin a series of dates with a great deal of entertainment, a moderate amount of food, and the merest suggestion of affection.  As the amount of affection increases, the entertainment can be reduced proportionately.  When the affection is the entertainment, we no longer call it dating.  Under no circumstances can the food be omitted.  ~Miss Manners’ Guide to Excruciatingly Correct Behaviour

Life without sex might be safer but

Life without sex might be safer but it would be unbearably dull.  It is the sex instinct which makes women seem beautiful, which they are once in a blue moon, and men seem wise and brave, which they never are at all.  Throttle it, denaturalize it, take it away, and human existence would be reduced to the prosaic, laborious, boresome, imbecile level of life in an anthill.  ~Henry Louis Mencken
