Coitus

Coitus, also known as sexual intercourse or copulation, refers to the act of sexual union between two individuals, typically involving the insertion of an erect penis into a vagina. This intimate physical activity is a fundamental aspect of human sexuality and serves both reproductive and pleasurable purposes. Coitus is often considered the primary means of sexual expression between partners and can be a significant component of emotional bonding.

Additional Information

While coitus traditionally refers to penile-vaginal intercourse, modern understanding of sexuality recognizes various forms of sexual activity as equally valid. Coitus can be practiced for reproduction, pleasure, or both. It involves a series of physiological responses in both partners, including arousal, plateau, orgasm, and resolution, known as the sexual response cycle.

The term "coitus" is derived from the Latin word "coire," meaning "to go together" or "to unite." It's important to note that safe sexual practices, including the use of contraception and protection against sexually transmitted infections (STIs), are crucial aspects of responsible coitus.
