Boning is a colloquial term for sexual intercourse, referring to the act of two individuals engaging in penetrative sex. This activity typically involves the insertion of the male's penis into the female's vagina, although it can also refer to other forms of sexual activity between partners of any gender. The term is often used informally and can imply a casual or non-committed relationship. It is important to note that safe practices, such as using condoms or other forms of protection, are essential to prevent sexually transmitted infections (STIs) and unintended pregnancies during sexual encounters.
