While this organ is the one upon which orgasm sits for all females, sensation for at least forty per cent of women, if not more is located exclusively there. These women, we shall refer to in the future as the "lowly sensitive''. Regarding this group, the other areas of the vulva, as well as the vaginal interior, are completely insensitive, and where any sensation at all exists there, it is so slight as to be fo no consequence.
Most unhappily, nature has committed an oversight here, as she occasionally does, and it is this, in addition to the difficulty more men in delaying orgasm, that contributes almost wholly to sexual incompatibility or lack of sexual satis-faction on the part of the female. Another third, approximatelu, to whom we shall refer as the 'moderately sensitive,'' have only a moderate sensitivity about the vulva, exclusive of the clitoris.
While this group is capable of orgasm indepen- dent of clitoral contact with the finger or penis, it relies largely upon a rapid, violent rhythm which sets up a disturbance in the entire genital area. This violent motion, characterized by deep pene- trations into the vagina, also has the power by the force of its drive to bring the area above the penis itself into contact with the clitoris and to create a strong aggrava- tion about the external parts above the vagina which may extend even to the clitoral zone.
Such a woman also characteris-tically engages in fierce genital wriggling, even meeting the male in his drive, as if to force the clitoris, and perhaps so doing on occasion, against the male organ and caused the penis to bend. If the male orgasm can be delayed, or rather delays itself long enough - this violent type of male makes no effort himself to exercise control, and movement of this kind will not allow to retarded male orgasm - the woman may have her climax, and it will usually occur simultaneously with that of the male. She may miss it, however, if she is slow to respond or if, following his orgasm, the male does not continue the rhythm long enough for her to reach her climax.
