Marie Stopes,
Married Love — Chapter 9: Children
(1918)
“ For two years after the birth of the child her vitality was so lowered that the sex act was to her so repugnant that she refused her husband any union; and it was thus three years after their marriage before they met in anything like a normal way. By that time the long separation from sex-life, and the strain on the man, coupled with daily familiarity at home, had dimmed, if not completely destroyed, his sense of romance. The natural stimulation each should exert on the other had faded, so that they never experienced the mutual glow of intense rapture in their sex-union. ”
