>The prostatic plexus contains some limited sensory receptors that travel with the autonomic nerves, but not many, and these receptors are not able to pick up a wide range of sensation.
>Myrtle Wilhite MD says no: “Massaging the gland itself (while it has health benefits of pushing some fluid out) does not lead to sexual arousal.” She suggests that what is really happening is that the autonomic nerves of the prostatic plexus are being massaged and the impact of this massage is not mediated by sensory receptors.

>The G-spot, a putative erogenous area in the anterior vaginal wall, is a widely accepted concept in the mainstream media, but controversial in medical literature.
[9] [_The Basic Writings of Sigmund Freud_](https://books.google.it/books?id=wv1GAAAAMAAJ)
>The chief erogenous zone in the female child is the clitoris, which is homologous to the male penis. All that I have been able to discover about masturbation in little girls refers to the clitoris,
>If one wishes to understand how the little girl becomes a woman, he must follow up the further destinies of this clitoris excitation. Puberty, which brings to the boy a great advance of libido, distinguishes itself in the girl by a new wave of repression, which especially concerns the clitoris sexuality. It is a part of the male sexual life that sinks into repression.
>If the woman finally submits to the sexual act, the clitoris becomes stimulated and its role is to conduct the excitement to the adjacent genital parts; it acts here like a chip of pinewood, which is utilized to set fire to the harder wood. It often takes some time before this transference is accomplished,
>If the transference of the erogenous excitability from the clitoris to the vaginal entrance succeeds, the woman then changes her leading zone for the future sexual activity; the man, on the other hand, retains his from childhood.
[13] [_The Role of Urethra in Female Orgasm_](http://www.andreadrian.de/Sex_und_Arbeitsteilung_Mann_Frau/1950_Graefenberg_The_Role_of_Urethra_in_Female_Orgasm.pdf)
>This I can confirm by my own experience of numerous women. An erotic zone always could be demonstrated on the anterior wall of the vagina along the course of the urethra.
>Analogous to the male urethra, the female urethra also seems to be surrounded by erectile tissues like the corpora cavernosa. In the course of sexual stimulation, the female urethra begins to enlarge and can be felt easily. It swells out greatly at the end of orgasm. The most stimulating part is located at the posterior urethra, where it arises from the neck of the bladder.
>Certain it is that this area in the anterior vaginal wall is a primary erotic zone, perhaps more important than the clitoris, which got its erotic supremacy only in the age of necking.
[19] [_Human Sexual Repsonse_](https://books.google.it/books/about/Human_Sexual_Response.html?id=NexqAAAAMAAJ)
>In addition, the clitoral body may be stimulated indirectly by natural or artificial coition with the female partner in the supine, superior, or knee chest position.
>However, when any woman experiences orgasmic response to effective sexual stimulation, the vagina and clitoris react in consistent physiologic patterns. Thus, clitoral and vaginal orgasms are not separate biologic entities.

>The increase in the pressure of the rectum calls for closure of the epiglottis, tightening the diaphragm, tightening the muscles of the chest wall, and stimulation of the parasympathetic nervous system. The initial results of bearing down are rise in arterial pressure and bradycardia, followed by a rapid fall in blood pressure and the subsequent decrease in blood flow to the brain. This is a normal response.
>Syncope accounts for 3%–5% of emergency room visits, and defecation syncope (DS) is infrequently described in the literature. DS describes the vasovagal response that occurs while defecating that results in a loss of consciousness

>however, anal penetration stimulates the vagus nerve, which leads to a slowed heart rate, rhythm, impulse conduction, and coronary blood flow, which can result in diminished cardiac performance and chest pain.
>Therefore, sexual counselling might include the avoidance of anal sex until the cardiac condition is stabilized and after further evaluation of the safety of sexual activity.
