Love is something far more than desire for sexual intercourse; it is the principal means of escape from the loneliness which afflicts most men and women throughout the greater part of their lives. Bertrand Russell
In human intercourse the tragedy begins, not when there is misunderstanding about words, but when silence is not understood. Henry David Thoreau
You think intercourse is a private act; it's not, it's a social act. Men are sexually predatory in life; and women are sexually manipulative. When two individuals come together and leave their gender outside the bedroom door, then they make love. Andrea Dworkin
We do not learn by inference and deduction and the application of mathematics to philosophy, but by direct intercourse and sympathy. Richard M. Nixon
Two nations between whom there is no intercourse and no sympathy; who are as ignorant of each other's habits, thoughts, and feelings, as if they were dwellers in different zones, or inhabitants of different planets. The rich and the poor. Benjamin Disraeli
