And the distance between the clitoris and the vaginal orifice or introitus vaginae is very different in different individuals, either because the clitoris is higher set and further forward than usual, or because the introitus is further back, i.e., nearer the anus. The glans clitoridis may be inclined towards the phallus as the latter enters the introitus by increasing the woman's pelvic angle. This means that the lumbar region is hollowed and the anterior or frontal portion of the pelvis—if the woman stands on her feet—slightly lowered. (The same movement is also possible in the recumbent and kneeling and sedentary attitudes, as we shall see.) And this further possibility introduces us to the use of the culture and control of the pelvic zone. We shall now, therefore, cease to deal with the pelvic floor, assuming as self-evident that its action can combine with and enhance the wider-ranging motions and positions of the pelvis—and, in fact, the body—as a whole. In order to realise the significance of this shifting pelvic angle or pelvic inclination which dips forward the lower abdomen and pubis, and brings the glans clitoridis sometimes into actual close contact with the dorsum penis (or upper surface of the phallus, e.g., in coitus performed in the first and usual attitude of the converse, or face to face position)— it should be known that women have two distinct and independent kinds of sexual pleasure or voluptas, localised respectively in clitoris and vagina (including orifice, inner walls and portio vaginalis of the womb). Either the clitoridal or the vaginal sensation may be aroused without the other, and may culminate in supreme ecstacy or orgasm, with subsequent relaxation and full satisfaction.* The perfect sexual communion should combine both * See " Ideal Marriage," p. 180 : " But the sensations differ as much between themselves as the flavour and aroma of two fine kinds of wine— or the chromatic glories and subtleties of two quite separate colour schemes. And even the orgasms induced by clitoridal or vaginal stimulation respec- tively are, curiously, though not widely, different, although the internal mechanism, the reflexes, the local and cerebral discharges and the ensuing relief may be equal and identical,"
