Tom Robbins said this quote
“ The protagonist, Amanda, discusses her sex relationship with her husband, John Paul --As long as it's done with honesty and grace, John Paul doesn't mind if I go to bed with other men. Or with other girls, as is sometimes my fancy. What has marriage got to do with it? Marriage is not a synonym for monogamy any more than monogamy is a synonym for ideal love. To live lightly on the earth, lovers and families must be more flexible and relaxed. The ritual of sex releases its magic inside or outside the marital bond. I approach that ritual with as much humility as possible and perform it whenever it seems appropriate. As for John Paul and me, a strange spurt of semen is not going to wash our love away. ”
