What is Sexual intercourse and Definition

Sexual activity that involves penetration between sexual partners. In conventional context sexual intercourse is the insertion of a man’s erect PENIS into a woman’s VAGINA and is the primary mechanism of human reproduction. Male EJACULATION propels SEMEN into the vagina, where the SPERM it contains may unite with an egg (ovum) if the woman is ovulating and conditions are conducive. In contemporary context the term more broadly encompasses vaginal sex, anal sex, and oral sex between partners of either gender as acts of intimacy and pleasure, physical and emotional, that may or may not include the intent to conceive a PREGNANCY.
