intromission

The said John, by letter, gave a discharge to the said Earl of all further intromission or care with his affairs.

As a respectable man, I, for one, would never countenance any intromission of that kind.

Courtship is consummated when the female raises her tail in acceptance of the male and intromission is effected.

His revelations considerably surprised me, because I had no idea that there was actual intromission.

The pair remained in the coital position for 30 minutes after the male had achieved intromission.
