Heterosexual coitus __Hetero-__ - heterosexual (Greek) Coitus: this is the name of sexual intercourse, in other words, the union of the genital organs of partners. In heterosexual coitus, the genital organs of a woman and a man are joined. There are also men who live without women, they are called ``gender non-binary'', or ``transgender women''. It is wrong to call such men women, so you need to use the word ``homosexual'' or in English ``LGBT+'' Heterosexual couples often ejaculate during coitus, because they are both more excited.
