Marie Stopes,
Married Love — Chapter 9: Children
(1918)
“ When two who are mated in every respect burn with the fire of the innumerable forces within them, which set their bodies longing toward each other with the desire to inter-penetrate and to encompass one another, the fusion joy and rapture is not purely physical. The half swooning sense of flux which overtakes the spirit in that moment at the apex of rapture sweeps into its tides the whole essence of the man and woman, and as it were, the heat of the contact vaporizes their consciousness so that it fills the whole of cosmic space. ”
