The following text is obtained from a 1918 copy of Marie Stopes' blockbuster Married Love , the pioneer classic on married women's sexuality and female sexuality in general.
Every heart desires a mate.
In all young people, unless they have inherited depraved or diseased faculties, the old desire of our race springs up afresh in its pristine beauty. With the dreams and bodily changes of adolescence, come to the youth and maiden the strange and powerful impulses of the racial instinct. The bodily differences of the two, now accentuated, become mystical, alluring, enchanting in their promise. In the modem world, those who set out on high endeavours or who consciously separate themselves from the ordinary course of social life, are comparatively few, and it is not to them that I am speaking. In the kisses and the hand touch of the betrothed are a zest and exhilaration which stir the blood like wine.
