In certain animals, sexual intercourse is not only used for reproduction, but has taken other functions as well. Most mammals only mate when the female is at the point of estrus, which is the most fertile period of time in its reproductive cycle. Two animals coming together for the purposes of sexual reproduction is called mating. Sex is usually teleiophilic (between adults). These behaviors are sometimes included in the definition of sexual intercourse. Humans sometimes engage in behaviors that do not include the penetration of sexual organs, such as oral intercourse or anal intercourse or by non-sexual organs ( fingering, fisting). Sexual intercourse may also be between individuals of the same sex. The two animals may be of opposite sexes or they may be hermaphroditic, as is the case with snails. Sometimes sexual intercourse is called coitus or copulation and is more casually known as having sex or sleeping together. People and animals that sexually reproduce use sexual intercourse to have an offspring. Sexual intercourse (or simply called sex) is the insertion and thrusting of a male's penis into a female's vagina.
