Copulation

Copulation, also known as sexual intercourse or coitus, is the act of sexual reproduction in which a penis is inserted into a vagina, typically resulting in the ejaculation of semen. This process allows for the potential fertilization of an egg, which can lead to pregnancy. While copulation is primarily associated with reproduction, it is also a common form of sexual expression and pleasure for many individuals and couples.

Additional Information

Copulation is a natural biological process that occurs in many species, including humans. In humans, it involves the stimulation of erogenous zones and often includes other forms of sexual activity such as foreplay. While copulation specifically refers to penis-in-vagina intercourse, it's important to note that there are many other forms of sexual activity that don't involve this specific act.

The duration and frequency of copulation can vary greatly among individuals and couples. Factors such as age, health, relationship status, and personal preferences can all influence copulatory practices. It's also worth noting that safe sex practices, such as the use of condoms or other contraceptives, are important for preventing unwanted pregnancies and the spread of sexually transmitted infections.
