A bit farther inside the female organ, along the centre of its front or top wall, you will find a narrow, lenghwise band where firm caresses cause intensive response. The base of the bladder and the urethra, which leads from the bladder to the body surface, lie in this area. They contain a rich network of nerve fibres which become keenly sensitive sexually after a few months of marriage. You will never feel or detect the specific structures which make this area sensitive since they lie underneath a substantial layer of tissue and have about the same consistency as the neighbouring organs.
However, you will be able to tell from your wife's response when your caresses stimulate them. The basic urethra-stimulating caress starts with the finger inserted two or three inches into the vagina. By presssing the fingertip frontward against the vagina's top wall, you can catch the urethra between your fingertip and the public bone. Keeping to the exact centre if possible, draw the fingertip outward until you reach the margin of the muscular, washi-board-surfaced vaginal wall. No narm will be done if you carry the caress a bit too far, but you should ease up on any substantial pressure before reaching the easily- hurt inner lips.
After you have located the sensitive area in the way, you can vary the procedure with inward strocking pressing the fingertip up against the public bone at the centre of the vagina's rim (starting distinctly inside from the inner lips) and milking the underlying structures upward. Both the urethra itself and the tissues surround- ing it are fairly sturdy, so firm friction cause no discomfort. Side-to-side movement of the finger also stimulates the urethra, but not as effectively as lengthwise stroking. You will ordinarily find one finger much more effective than two for urethral caress, since the sensitive structures lie in the exact midline where the groove between joined fingers tends almost automatically to fall. Slow stroking is just as effective and much easier to manage than rapid titillation.
Urethral caress usually proves highly exciting and generally brings a woman quickly to the high plateau of keen enjoyment which many experienced women treasure much more than orgasm itself. At this point, return to gentle titillations of the inner lips and other forms of foundling sustain excitement very well, making continuous urethral caress unnecessary. You usually find this measure best used like booster rockets on an aeroplane, to bring your wife to a high plane of excitement quickly so that other, midler measures can take over and keep her there.
