copulation

The act of coupling or joining; union; conjunction.

I quite correctly defined logical copulation by means [of] the copula of inclusion.

Sexual procreation between a man and a woman or transfer of the sperm from male to female; usually applied to the mating process in nonhuman animals; coitus; coition.

Solomon, who was one of the Deity's favorities, had a copulation cabinet composed of seven hundred wives and three hundred concubines.

In the dusky streets around me ruled an innocent and open copulation. The entire town mated together, in the leafy bowers that had sprung up among the washing-machines and television sets in the shopping mall, on the settees and divans by the furniture store, in the tropical paradises of the suburban gardens.
