IUD is a contraceptive that men do not use. IUD stands for intrauterine device. It is a small contraceptive device that is inserted into the uterus.
Sex is not a way to D. ALL OF THE ABOVE. It is not a way to prove your love. It should not be used to increase self-worth. It should not be used to bargain for attention.
Sexual intercourse's primary purpose is to procreate, as God has commanded. It is a physical affirmation of your love to your spouse.
