In human intercourse the tragedy begins, not when there is misunderstanding about words, but when silence is not understood. Henry David Thoreau
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
War is not merely a political act but a real political instrument, a continuation of political intercourse, a carrying out of the same by other means. Carl von Clausewitz
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
