Genital stimulation during the time of menstrual flow may be ill-advised. Both changes may diminish positive penile sensations as well as the woman's source of sensory stimulation and effector neurons. Hence, a time to refrain may lead to a more satisfactory sex life for both men and women. Back to the top. A time for changing the pattern of stimulation is worthy of study given life changes in sex hormones, blood flow, and neural processes.
Many questions remain.
For heterosexual women, the sensory responses to genital stimulation are dependent on the skill of her male partner and his understanding of female physiology. Since orgasm was not relevant to the estrogen changes or the fertility relationships in the cited studies, a man's pheromones rather than his sensual skills most likely account for some substantial stimulatory component in achieving these relationships. However, adequate sensory stimulation may increase the likelihood that a woman will be willing to engage in regular genital stimulation in the presence of a man. Thus, appropriate timing accounts for many positive outcomes. Second edition Athena Institute Press, 1996.
