When young, there is almost only one area of male sexual sensitivity, which is the genitals. You should treat the 'second' well, that's enough. Stroking his shoulders, chest, legs, and backs, he may feel like it's unnecessary. Young women, on the other hand, have sexually sensitive areas almost all over their bodies. A considerable number of young women can exhibit strong sexual reactions as long as the sensitive areas around them are appropriately and adequately stimulated.
So, young wives crave to be fully, delicately, and persistently caressed. The conflicts and disappointments that some people experience on their wedding night are mostly related to the differences in gender sensitive areas between men and women.
As men age, their physical strength and sexual desire gradually decline, making them often reluctant to engage in sexual activity. To conceal embarrassment and regroup, it is often necessary to be stimulated from the periphery of the body, then gradually concentrate towards the center, and finally engage in sexual activity.
Over time, the sensitive area gradually expands from the center to the surrounding area, gradually spreading throughout the body. Men also increasingly crave to be caressed fully, delicately, and persistently.
Middle aged women, on the contrary, enter the "Year of the Wolf and Tiger" because their spirit and flesh are gradually unbound, and their preparation time for sexual life is becoming shorter and shorter, requiring direct and strong stimulation during sexual life.
Therefore, they involuntarily focus their sensory abilities more and more on the genitals and a few other body parts, and the sexually sensitive areas that are spread throughout the body are also increasingly concentrated towards the sexual organs.
