Anal Masturbation
Anal masturbation is an autoerotic practice in which a person masturbates by sexually stimulating their own anus and rectum. Common methods of anal masturbation include manual stimulation of the anal opening and the insertion of an object or objects. Items inserted may be sex toys such as anal beads, butt plugs, dildos, vibrators, rectal thermometers or specially designed prostate massagers or enemas. Method Pleasure can be derived from anal masturbation due to the nerve endings in the anal and rectal areas. Men In men, orgasmic function through genitalia depends in part on the healthy functioning of the smooth muscles surrounding the prostate, and of the pelvic floor muscles. Anal masturbation can be especially pleasurable for those with a functioning prostate because it often stimulates the area, which also contains sensitive nerve endings. Some men find the quality of their orgasm to be significantly enhanced by the use of a butt plug or other anally inserted item du ...

Male Anatomy 1
Male (symbol: ♂) is the sex of an organism that produces the gamete (sex cell) known as sperm, which fuses with the larger female gamete, or ovum, in the process of fertilisation. A male organism cannot reproduce sexually without access to at least one ovum from a female, but some organisms can reproduce both sexually and asexually. Most male mammals, including male humans, have a Y chromosome, which codes for the production of larger amounts of testosterone to develop male reproductive organs. In humans, the word ''male'' can also be used to refer to gender, in the social sense of gender role or gender identity. Overview The existence of separate sexes has evolved independently at different times and in different lineages, an example of convergent evolution. The repeated pattern is sexual reproduction in isogamous species with two or more mating types with gametes of identical form and behavior (but different at the molecular level) to anisogamous species with gametes o ...

Prostate
The prostate is an male accessory gland, accessory gland of the male reproductive system and a muscle-driven mechanical switch between urination and ejaculation. It is found in all male mammals. It differs between species anatomically, chemically, and physiologically. Anatomically, the prostate is found below the bladder, with the urethra passing through it. It is described in gross anatomy as consisting of lobes and in microanatomy by zone. It is surrounded by an elastic, fibromuscular capsule and contains glandular tissue, as well as connective tissue. The prostate produces and contains fluid that forms part of semen, the substance emitted during ejaculation as part of the male human sexual response cycle, sexual response. This prostatic fluid is slightly Alkalinity, alkaline, milky or white in appearance. The alkalinity of semen helps neutralize the acidity of the vagina, vaginal tract, prolonging the lifespan of sperm. The prostatic fluid is expelled in the first part of ej ...

Peritoneal Cavity
The peritoneal cavity is a potential space located between the two layers of the peritoneum—the parietal peritoneum, the serous membrane that lines the abdominal wall, and visceral peritoneum, which surrounds the internal organs. While situated within the abdominal cavity, the term ''peritoneal cavity'' specifically refers to the potential space enclosed by these peritoneal membranes. The cavity contains a thin layer of lubricating serous fluid that enables the organs to move smoothly against each other, facilitating the movement and expansion of internal organs during digestion. The parietal and visceral peritonea are named according to their location and function. The peritoneal cavity, derived from the coelomic cavity in the embryo, is one of several body cavities, including the pleural cavities surrounding the lungs and the pericardial cavity around the heart. The peritoneal cavity is the largest serosal sac and fluid-filled cavity in the body, it secretes approximately ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Microorganism
A microorganism, or microbe, is an organism of microscopic scale, microscopic size, which may exist in its unicellular organism, single-celled form or as a Colony (biology)#Microbial colonies, colony of cells. The possible existence of unseen microbial life was suspected from antiquity, with an early attestation in Jain literature authored in 6th-century BC India. The scientific study of microorganisms began with their observation under the microscope in the 1670s by Anton van Leeuwenhoek. In the 1850s, Louis Pasteur found that microorganisms caused food spoilage, debunking the theory of spontaneous generation. In the 1880s, Robert Koch discovered that microorganisms caused the diseases tuberculosis, cholera, diphtheria, and anthrax. Microorganisms are extremely diverse, representing most unicellular organisms in all three domains of life: two of the three domains, Archaea and Bacteria, only contain microorganisms. The third domain, Eukaryota, includes all multicellular o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buttplug
A butt plug is a sex toy that is designed to be inserted into the rectum for sexual pleasure. They often have a flanged end to prevent the device from being lost inside the rectum. History Rectal dilators were originally designed for therapeutic uses and later marketed with terms such as Dr. Young's Ideal Rectal Dilators, which were marketed as a cure for insanity and constipation. In the late 20th century, similar devices started to be marketed as sex toys. Basics Unlike the vagina, which is closed off by the cervix, the rectum leads to the sigmoid colon. Objects that are inserted into the rectum can therefore potentially travel up into the bowel; the flared end on a butt plug exists to prevent this. Some dildos lack a flared end, and thus it is not advised to use such dildos anally since they may get stuck; rectal foreign bodies may require medical extraction. In addition, the lower bowel above the rectum is easily perforated. For this reason, butt plugs tend to be shorter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Penis
In Human body, human anatomy, the penis (; : penises or penes; from the Latin ''pēnis'', initially 'tail') is an external sex organ (intromittent organ) through which males urination, urinate and ejaculation, ejaculate, as Penis, on other animals. Together with the testes and surrounding structures, the penis functions as part of the male reproductive system. The main parts of the penis are the Root of penis, root, Body of penis, body, the epithelium of the penis, including the shaft skin, and the foreskin covering the glans penis, glans. The body of the penis is made up of three columns of tissue (biology), tissue: two Corpus cavernosum penis, corpora cavernosa on the dorsal side and corpus spongiosum penis, corpus spongiosum between them on the ventral side. The Urethra#Male, urethra passes through the prostate gland, where it is joined by the ejaculatory ducts, and then through the penis. The urethra goes across the corpus spongiosum and ends at the tip of the glans as the o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anal Douche
Rectal douching is the act of rinsing the rectum with intent to clean it. An instance of this rinsing or a tool used to perform the rinse may be called a rectal douche. Uses Rectal douching is a hygienic practice to clean the rectum to void hardened stools as opposed to a pharmaceutical method to soften the stool. Rectal douching is distinguished from anal cleansing, which is the routine cleaning of the anus after defecation. Risks Evidence is not clear, but it is possible that rectal douching before anal sex can increase the risk of transferring HIV, and other diseases. There is evidence that douching sometimes can disrupt the epithelium, or tissue in the rectum, and if this tissue is damaged, then diseases can spread more easily. Rectal douching before anal sex increases the risk of transfer of Hepatitis B. There are reports that activities which can have the side effect of causing unintentional forcing of water into the rectum, such as waterskiing, may cause discomfort but ...

Klismaphilia
Klismaphilia (or klysmaphilia), from the Greek words ("enema", from , "deluge, flood") and ("love"), is a paraphilia involving enjoyment of, and sexual arousal from, enemas. History The term ''klismaphilia'' was coined in 1973 by Joanne Denko, an early investigator in this field, in her article "Klismaphilia: Enema as a Sexual Preference: Report of Two Cases," to describe the activities of some of her patients, whom she referred to as ''klismaphiliacs''. ''Klismaphile'' has come into use as a synonym for klismaphiliac. Manifestation Klismaphiles might gain pleasure from a large, water distended belly or the feeling of internal pressure. An enema fetish may include the sexual attraction to the equipment, processes, environments, situations, or scenarios, and some may be sexually aroused by the preparations, such as by the feel and smell of a latex rubber or plastic syringe, by the smell of soapsuds enema solution, or by preparing the recipient.Agnew, ''Klismaphilia (2000)'':75 ...

Alfred Kinsey
Alfred Charles Kinsey (; June 23, 1894 – August 25, 1956) was an American sexologist, biologist, and professor of entomology and zoology who, in 1947, founded the Institute for Sex Research at Indiana University, now known as the Kinsey Institute for Research in Sex, Gender, and Reproduction. He is best known for writing ''Sexual Behavior in the Human Male'' (1948) and ''Sexual Behavior in the Human Female'' (1953), also known as the Kinsey Reports, as well as for the Kinsey scale. Kinsey's research on human sexuality, foundational to the field of sexology, provoked controversy in the 1940s and 1950s, and has continued to provoke controversy decades after his death. His work has influenced social and cultural values in the United States as well as internationally. Early life and education Alfred Kinsey was born on June 23, 1894, in Hoboken, New Jersey, the son of Sarah Ann ( Charles) and Alfred Seguine Kinsey. He was the eldest of three children.
