Anatomy of the Female arousal cycle Part 1 (Work in progress)
The clitoris is like a tiny button protruding from under the clitoral hood.

The g-spot has entered the realm of sexual folklore. It is described as a magical spot that allows women to achieve orgasms within their vagina, from penetrative stimulation. Many doubt its existence, since not every woman has been able to achieve one.
First, let us review a quick history of the g-spot. Freud was the first person to popularize the idea of the vaginal orgasm. He believed that the clitoral orgasm is an immature version of the vaginal orgasm, which women are supposed to naturally switch to upon puberty. I often call this "the words that set off a million fake orgasms". Freud's theory left a huge number of women feeling inadequate, since so many could not achieve a vaginal orgasm, let alone any orgasm. Today, most of Freud's theories have been debunked, and even openly mocked, by the psychological community, including this one. After Freud, a man named Ernst Grafenberg came along. He believed he found a spot inside a woman that could be stimulated to cause an orgasm "from the inside". This finding was from studying stimulation through the female urethra, but gained vast popularity within the public as a form of orgasm through stimulation within the vaginal canal. The subject is still debated, but it is becoming more widely accepted as an actual erogenous zone.
The g-spot is supposedly 1 to 2 inches inside the vaginal canal, just before what is often described as a "spongy golf-ball-sized object". From viewing the diagram above, you can see that the g-spot is theorized to be right before a dip in the vaginal canal that is caused by the bladder. Common ways to stimulate this spot is through use of one's fingers, through intercourse, or using toys.
THE DEEP SPOTS

The next section has to do with a subject that is frequently misunderstood, and not commonly known. The term "deep spot" was popularized by David Shade, a PUA and seduction specialist. Originally, he described the deep spot as a ring around the cervix where a woman is uniquely sensitive. As information poured out about erogenous zones that were already labelled around the same locations, he redefined the deep spot as existing within the "cavity of the cervix". This definition grew to include two spots, one on the anterior and one on the posterior walls of the vagina. Unfortunately, for David Shade, these spots had already been named...
Arousal and its importance to the deep spots: As a woman is aroused, her vagina lengthens and dilates. This is a process known as vaginal tenting, or ballooning. Often, during initial arousal, the vagina extends from approximately 3 inches to 5 or 6 inches deep. Since the vagina is a potential space, when a penis enters, it attempts to accommodate its size, lengthening to around 7 to 8 inches deep. One of the late stages of vaginal tenting (and lengthening) causes the cervix to back up and ascend slightly. This opens up a new portion of the vagina. This portion can be described as a "cavity" much as David Shade has described it. Within, one can find two "cavities" that be stimulated.
Anterior Fornix Erogenous Zone (AFE Zone)
This erogenous zone can be found along the anterior wall. It is within the anterior fornix, a cavity in the anterior wall deep within the vaginal canal. It is often called the A-Spot or epicentre. It also is the location of the recto-uterine pouch.
Posterior Fornix Erogenous Zone (PFE Zone)
This erogenous zone can be found along the posterior wall. It is within the posterior fornix, but differs anatomically from the anterior fornix. First of all, this space is a bit deeper. This spot is also called the U-Spot or Cul-de-Sac. It can also be stimulated from the anus. Stimulation to the PFE Zone is often connected to the sudden onset of the female ejaculatory response, although many women can "squirt" with stimulation to other spots. Some women will not "squirt" even with this spot.
The names of these two spots are often mixed up. Whether there is a major difference between the spots is not clear.
Research also suggests [Rabinerson D, Horowitz E (February 2007). "[G-spot and female ejaculation: fiction or reality?]" (in Hebrew). Harefuah 146 (2): 145–7, 163. PMID 17352286 ] that when a female ejacualtes, the source is from the Skene's gland
The Skene's Gland is now also referred to as the female prostate. The Skene's Gland is somewhere around the vulva and is believed to be responsible for the release of female ejaculatory fluid. It is connected to why the g-spot may cause squirting, as the neural cluster known as the g-spot is located just below the bladder, much as the prostate is in males. I personally believe that something was missed in this assessment, as it is clear the recto-uterine pouch seems to be even more connected to squirting. It is currently believed the recto-uterine pouch is the same as the recto-vesicular pouch. Since the recto-vesicular pouch in males is located right next to the seminal vesicles, I think that the the large number of neurons that can be found in the prostate also exist at the recto-uterine pouch. This fits with why the deep spots have a stronger connection to squirting. The reason the PFE may be more connected to squirting than the AFE is possibly just because it is easier to effectively aim for. Essentially, what I believe, as do many others, is that a neural cluster exists around the deep spot that would originally have been the prostate. My belief is supported by one other theory...
The clitoral root is a path of neurons that run from the clitoris, up the tissue that lines the anterior wall of the vagina. Research into it has led to the development of the theory that the g-spot is a unique location along the vaginal anterior wall where the neurons collect most, and dip down closest, to the inside of the vaginal canal. The basic idea is that the neurons are not "in" the vagina, but are inside the tissue slightly above it, so proper pressure from within the vagina can stimulate this neural path. Pressure on different parts of this neural path will feel different, which accounts for the different feelings a woman can get from a g-spot orgasm and a clitoral orgasm. One can also gather from this, that the same clitoral root may be responsible for orgasms from the a-spot. Since all the neurons and muscles are bundled within and around the vagina, any sensation within one part can trigger similar reactions in others. This explains why squirting can happen regardless of the stimulated area, whether it is the clitoris, g-spot, a-spot, or u-spot.
The pelvic floor muscles are responsible for the contractions within the vagina during arousal, tenting, and orgasm. These same muscles are what collect blood to the pelvic region, and possibly aid in triggering neural stimulation. In men, we see the pelvic floor squeeze on the cluster of neurons surrounding the prostate within the rectum, as a man reaches orgasm. Within women, orgasms are much more subtle, but there have been correlations made between pelvic floor muscles and the female orgasm.
Firstly, it has been shown that women who have stronger pelvic floors are more readily able to experience vaginal orgasms. Whether this strengthens their already existing orgasms, makes these types of orgasms more frequent, or even gives a woman her first vaginal orgasm all depends on the individual.
Second, a connection between a strong pelvic floor and squirting has been made. The stronger the pelvic floor, the more likely the squirter, but not always.
Third, women with uniquely strong pelvic floors have shown a unique ability: they can masturbate by simply flexing their PC muscles. Imagine a woman flexing repeatedly to stimulate her clitoral root over and over again. This is actually done by using the muscles to clench down on the tissue surrounding the neural path from the clitoris. As a woman does this, she can slowly stimulate herself to orgasm. This third point brilliantly illustrates the connection between the clitoral root, pelvic floor muscles, and vaginal orgasms.0 Likes, 0 Thanks
