Food is necessary for the life of an individual, and marriage is necessary for the life of humanity. If eating to excess is evil for an individual, then excess in marriage and sexuality create evil for both individual and human society.
A marriage is a special obligation between two people, of opposite sexes, to have children only with each other. To break this pact is a lie, a deception, and a crime.
In is a great thing when two souls are united to support each other in their work, in their successes and misfortunes, until the last silent minutes of the last good bye.
GEORGE ELIOT
The Pharisees also came unto him, tempting him, and saying unto him, is it lawful for a man to put away his wife for every cause? And he answered and said unto them, have ye not read, that He which made them at the beginning made them male and female, and said, For this cause shall a man leave father and mother, and shall cleave to his wife: and the twain shall be one flesh? Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let no man put asunder.
Matthew 19-3-6
The unification of a man and a woman for the continuation of humankind is a great and important deed for every individual, as well as for all mankind. You cannot do it as it pleases you, or as you like it. You have to do it in the way which was thought and set out by the wise and holy people who have lived before us.
