The above opinions of seventeenth-century physicians are quoted from the original sources. Schurig, in his Gynæcologia, (pp. 46-50 and 71-81), quotes a number of passages on this subject from medical authorities of the same period, on which I have not drawn.
Sénancour, in his fine and suggestive book on love, first published in 1806, asks: "Has sexual pleasure the same power on the sex which less loudly demands it? It has more, at all events in some respects. The very vigor and laboriousness of men may lead them to neglect love, but the constant cares of maternity make women feel how important it must ever be to them. We must remember also that in men the special emotions of love only have a single focus, while in women the organs of lactation are united to those of conception. Our feelings are all determined by these material causes." (Sénancour, De l'Amour, fourth edition, 1834, vol. i, p. 68.) A later psychologist of love, this time a woman, Ellen Key, states that woman's erotic demands, though more silent than man's, are stronger. (Ellen Key, Ueber Liebe und Ehe, p. 138.)
Michael Ryan considered that sexual enjoyment "is more delicious and protracted" in women, and ascribed this to a more sensitive nervous system, a finer and more delicate skin, more acute feelings, and the fact that in women the mammæ are the seat of a vivid sensibility in sympathy with the uterus. (M. Ryan, Philosophy of Marriage, 1837, p. 153.)
Busch was inclined to think women have greater sexual pleasure than men. (D. W. H. Busch, Das Geschlechtsleben des Weibes, 1839, vol. i, p. 69.) Kobelt held that the anatomical conformation of the sexual organs in women led to the conclusion that this must be the case.
Guttceit, speaking of his thirty years' medical experience in Russia, says: "In Russia at all events, a girl, as very many have acknowledged to me, cannot resist the ever stronger impulses of sex beyond the twenty-second or twenty-third year. And if she cannot do so in natural ways she adopts artificial ways. The belief that the feminine sex feels the stimulus of sex less than the male is quite false." (Guttceit, Dreissig Jahre Praxis, 1873, theil i, p. 313.)
In Scandinavia, according to Vedeler, the sexual emotions are at least as strong in women as in men (Vedeler, "De Impotentia Feminarum," Norsk Magazin for Laegevidenskaben, March, 1894). In Sweden, Dr. Eklund, of Stockholm, remarking that from 25 to 33 per cent. of the births are illegitimate, adds: "We hardly ever hear anyone talk of a woman having been seduced, simply because the lust is at the worst in the woman, who, as a rule, is the seducing party." (Eklund, Transactions of the American Association of Obstetricians, Philadelphia, 1892, p. 307.)
On the opposite side of the Baltic, in the Königsberg district, the same observation has been made. Intercourse before marriage is the rule in most villages of this agricultural district, among the working classes, with or without intention of subsequent marriage; "the girls are often the seducing parties, or at least very willing; they seek to bind their lovers to them and compel them to marriage." In the Köslin district of Pomerania, where intercourse between the girls and youths is common, the girls come to the youths' rooms even more frequently than the youths to the girls'. In some of the Dantzig districts the girls give themselves to the youths, and even seduce them, sometimes, but not always, with a view of marriage. (Wittenberg, Die geschlechtsittlichen Verhalten der Landbewohner im Deutschen Reiche, 1895, Bd. i, pp. 47, 61, 83.)
Mantegazza devoted great attention to this point in several of the works he published during fifty years, and was decidedly of the opinion that the sexual emotions are much stronger in women than in men, and that women have much more enjoyment in sexual intercourse. In his Fisiologia del Piacere he supports this view, and refers to the greater complexity of the genital apparatus in women (as well as its larger surface and more protected position), to what he considers to be the keener sensibility of women generally, to the passivity of women, etc.; and he considers that sexual pleasure is rendered more seductive to women by the mystery in which it is veiled for them by modesty and our social habits. In a more recent work (Fisiologia della Donna, cap. viii) Mantegazza returns to this subject, and remarks that long experience, while confirming his early opinion, has modified it to the extent that he now believes that, as compared with men, the sexual emotions of women vary within far wider limits. Among men few are quite insensitive to the physical pleasures of love, while, on the other hand, few are thrown by the violence of its emotional manifestations into a state of syncope or convulsions. Among women, while some are absolutely insensitive, others (as in cases with which he was acquainted) are so violently excited by the paradise of physical love that, after the sexual embrace, they faint or fall into a cataleptic condition for several hours.
"Physical sex is a larger factor in the life of the woman.... If this be true of the physical element, it is equally true of the mental element." (Dr. Elizabeth Blackwell, The Human Element in Sex, fifth edition, 1894, p. 47.)
"In the female sex," remarks Clouston, "reproduction is a more dominant function of the organism than in the male, and has far larger, if not more intense, relationships to feeling, judgment, and volition." (Clouston, Neuroses of Development, 1891.)
