See, e.g., Féré, L'Instinct Sexuel, pp. 222-23: Brantôme was probably the first writer in modern times who referred to this phenomenon. MacGillicuddy (Functional Disorders of the Nervous System in Women, p. 110) refers to the case of a lady who always had sudden and uncontrollable expulsion of urine whenever her husband even began to perform the marital act, on which account he finally ceased intercourse with her. Kubary states that in Ponape (Western Carolines) the men are accustomed to titillate the vulva of their women with the tongue until the excitement is so intense that involuntary emission of urine takes place; this is regarded as the proper moment for intercourse.
