sexual intercourse between a male and female in which there is at least some slight penetration of the woman's vagina by the man's penis. It is legally significant in that it is a necessary legal characteristic or element of rape, child molestation, or consensual sexual relations with a girl below the age of consent ("statutory rape"). Age of consent varies from 14 to 18, depending upon the state.
