What is nakadashi meaning?

Nakadashi is a term used in Japanese pornography that refers to the act of ejaculating inside the vagina of a female partner during sexual intercourse without the use of any contraceptive device. The term literally means "internal ejaculation" in English. The act of nakadashi is often considered risky, as it may lead to unintended pregnancy or the transmission of sexually transmitted infections if proper precautions are not taken. Nakadashi is a common theme in Japanese adult videos, and some sexual partners may engage in the practice as a form of eroticism or sexual pleasure.
