Paul suggested that marriage was not just for procreation, 1 Corinthians 7:
Sex outside of marriage is a sin.
If you are burned with sexual desires, get married. Contraception is fine. Vasectomy is fine. Talk to God about it first. The usual practice is for married couples to have children.9 But if they cannot control themselves, they should marry, for it is better to marry than to burn with passion.
Sex outside of marriage is a sin.
