An interesting excerpt I stumbled upon from a female author in the 1960's about her exercising her sexuality.

"Here was a woman who sought the freedom to act out her sexual and emotional desires with the same guiltless, "amoral" abandon that men have always claimed for themselves."

“Man can never know the loneliness a woman knows. Man lies in the woman's womb only to gather strength, he nourishes himself from this fusion, and then he rises and goes into the world, into his work, into battle, into art. He is not lonely. He is busy. The memory of the swim in amniotic fluid gives him energy, completion. Woman may be busy too, but she feels empty. Sensuality for her is not only a wave of pleasure in which she is bathed, and a charge of electric joy at contact with another. When man lies in her womb, she is fulfilled, each act of love a taking of man within her, an act of birth and rebirth, of child rearing and man bearing. Man lies in her womb and is reborn each time anew with a desire to act, to be. But for woman, the climax is not in the birth, but in the moment man rests inside of her.” ― Anaïs Nin, The Diary of Anaïs Nin, Vol. 1: 1931-1934
