[10] A quotation from Thomas (p. 112 of William Thomas' book "Sex and Society," 1907, Pp. 314) is here very apt, though he had been speaking not of man, but of the love play and coyness shown by female birds and animals.
"We must also recognise the fact that reproductive life must be connected with violent stimulation, or it would be neglected and the species would become extinct; and on the other hand, if the conquest of the female were too easy, sexual life would be in danger of becoming a play interest and a dissipation, destructive of energy and fatal to the species. Working, we may assume, by a process of selection and survival, nature has both secured and safeguarded reproduction. The female will not submit to seizure except in a high state of nervous excitation (as is seen especially well in the wooing of birds), while the male must conduct himself in such a way as to manipulate the female; and, as the more active agent, he develops a marvellous display of technique for this purpose. This is offset by the coyness and coquetry of the female, by which she equally attracts and fascinates the male, and practises upon him to induce a corresponding state of nervous excitation."
