Orgasmic capacities via the vagus nerve
But what those research sites don’t often say is that not only does it [the vagus nerve] innervate the throat and chest, it is directly connected to the cervix and uterus. What does this mean for women’s pleasure? Beverly Whipple and Barry Komisaruk have investigated the vagus nerve and deep vaginal orgasms in women who have spinal cord injuries. This spinal cord compromise causes them to lack feeling in their lower extremities, thus not allowing them the capacity to feel orgasms by other nerve structures (There are four major nerve pathways to orgasm for women and three for men). The vagus nerve doesn’t travel through the spinal cord, however. Deep, penetrative sexual activities that affect the cervix and stimulate the uterus trigger orgasm via this nerve. These women can have and feel the orgasms.
Here is what I am speculating: That opening up the mouth, chest cavity (through slow, deep breathing) and orgasmic capacities via the vagus nerve may lead to powerful orgasms and possibly multiples and female ejaculation. When women emit deep, low sounds from their abdomens and with their mouths wide open this can sometimes lead to longer lasting, powerful orgasms and even female ejaculation. This all makes sense if you consider that the vagus nerve connects all of these functions, throat, chest, cervix and uterus, and that when they are utilized to the fullest extent of the nerve, and all of its endings, the nerve becomes so activated that it produces out of body pleasure that is more than the sum of its parts, so to speak.
