Frotting
Frot or frotting (slang for frottage; ) is a sexual practice that usually involves direct penis-to-penis contact. The term was popularized by gay male activists who disparaged the practice of anal sex, but has since evolved to encompass a variety of preferences for the act, which may or may not imply particular attitudes towards other sexual activities. This can also be used as some type of foreplay. Because it is not penetrative, frotting has the safe sex benefit of reducing the risk of transmitting HIV/AIDS; however, it still carries the risk of skin-to-skin sexually transmitted infections, such as HPV and pubic lice (crabs), both of which can be transmitted even when lesions are not visible. It is analogous to tribadism, which is vulva-to-vulva contact between women. Concept and etymology The modern definition of ''frotting'' emerged in a context of a debate about the status of anal sex within the gay male community; some in the anti-anal, pro-frotting camp insist that ...

Pre-ejaculate
Pre-ejaculate (also known as pre-ejaculatory fluid, pre-seminal fluid or Cowper's fluid, and colloquially as pre-cum) is a clear, colorless, viscous fluid that is emitted from the urethra of the penis during sexual arousal and in general during sexual activity. It is similar in composition to semen but has distinct chemical differences. The presence of sperm in the fluid varies from low to absent. Pre-ejaculate functions as a lubricant and an acid neutralizer. Origin and composition The fluid is discharged from the urethra of the penis during arousal, masturbation, foreplay or at an early stage during sexual intercourse, some time before the individual fully reaches orgasm and semen is ejaculated. It is primarily produced by the bulbourethral glands (Cowper's glands), with the glands of Littré (the mucus-secreting urethral glands) also contributing. The amount of fluid that is issued varies widely among individuals. Some individuals do not produce any pre-ejaculate fluid, ...

Mucous Membrane
A mucous membrane or mucosa is a membrane that lines various cavities in the body of an organism and covers the surface of internal organs. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue. It is mostly of endodermal origin and is continuous with the skin at body openings such as the eyes, eyelids, ears, inside the nose, inside the mouth, lips, the genital areas, the urethral opening and the anus. Some mucous membranes secrete mucus, a thick protective fluid. The function of the membrane is to stop pathogens and dirt from entering the body and to prevent bodily tissues from becoming dehydrated. Structure The mucosa is composed of one or more layers of epithelial cells that secrete mucus, and an underlying lamina propria of loose connective tissue. The type of cells and type of mucus secreted vary from organ to organ and each can differ along a given tract. Mucous membranes line the digestive, respiratory and rep ...

Sexually Transmitted Infection
A sexually transmitted infection (STI), also referred to as a sexually transmitted disease (STD) and the older term venereal disease (VD), is an infection that is Transmission (medicine), spread by Human sexual activity, sexual activity, especially Sexual intercourse, vaginal intercourse, anal sex, oral sex, or sometimes Non-penetrative sex#Manual sex, manual sex. STIs often do not initially cause symptoms, which results in a risk of transmitting them to others. The term ''sexually transmitted infection'' is generally preferred over ''sexually transmitted disease'' or ''venereal disease'', as it includes cases with no Signs and symptoms#Symptomatic, symptomatic disease. Symptoms and signs of STIs may include vaginal discharge, penile discharge, genital ulcers, ulcers on or around the genitals, and pelvic pain. Some STIs can cause infertility. Bacterial STIs include Chlamydia infection, chlamydia, gonorrhea, and syphilis. Viral STIs include genital warts, genital herpes, and ...

Glans Penis
In male human anatomy, the glans penis or penile glans, commonly referred to as the glans, (; from Latin ''glans'' meaning "acorn") is the bulbous structure at the Anatomical terms of location#Proximal and distal, distal end of the human penis that is the human male's most sensitive erogenous zone and primary anatomical source of Human sexuality, sexual pleasure. The glans penis is present in the male reproductive system, reproductive organs of humans and most other mammals where it may appear smooth, spiny, elongated or divided. It is externally lined with Mucosa, mucosal tissue, which creates a smooth texture and glossy appearance. In humans, the glans is located over the distal ends of the Corpus cavernosum penis, corpora cavernosa and is a continuation of the Corpus spongiosum (penis), corpus spongiosum of the penis. At the summit appears the urinary meatus and at the base forms the Corona of glans penis, corona glandis. An elastic band of tissue, known as the Penile frenulum ...

External Urethral Orifice (male)
The urinary meatus (, ; : meati or meatuses), also known as the external urethral orifice, is the opening of the penis or vulva where urine exits the urethra during urination. It is also where semen exits during male ejaculation, and other fluids during female ejaculation. The meatus has varying degrees of sensitivity to touch. In human males The male external urethral orifice is the external opening of the urethra, normally located at the tip of the glans penis, at its junction with the frenular delta. It presents as a vertical slit, and continues longitudinally along the front aspect of the glans, which facilitates micturition. In some cases, the opening may be more rounded. This can occur naturally or may also occur as a side effect of excessive skin removal during circumcision. The meatus is a sensitive part of the male reproductive system. In human females The female external urethral orifice is where urine exits the urethra during urination. It is located about behin ...

Frenulum Of Prepuce Of Penis
The frenulum of the penis, often known simply as the frenulum (from ) or frenum, is a thin elastic strip of tissue on the underside of the glans and the neck of the human penis. In men who are not circumcised, it also connects the foreskin to the glans and the ventral mucosa. In adults, the frenulum is typically supple enough to allow manual movement of the foreskin over the glans and help retract the foreskin during erection. In flaccid state, it tightens to narrow the foreskin opening. The penile frenulum is homologous to the clitoral frenulum in the female. It is similar to the lingual frenulum between the tongue's lower surface and the lower jaw, or the frenulum between the upper lip and the outside of the upper gum. In some men, the frenulum may appear shorter than normal, a phenomenon known as frenulum breve. Treatment of frenulum breve may be non-surgical, or in other cases, especially with penile chordee, it may include frenulectomy or frenulum lengthening. Structu ...

Non-penetrative Sex
Non-penetrative sex or outercourse is Human sexual activity, sexual activity that usually does not include sexual penetration, but some forms, particularly when termed ''outercourse'', include penetrative aspects, that may result from forms of fingering (sexual act), fingering or oral sex.

Fellatio
Fellatio (also known as fellation, and in slang as blowjob, BJ, giving head, or sucking off) is an oral sex act consisting of the stimulation of a human penis, penis by using the mouth. Oral stimulation of the scrotum may also be termed ''fellatio'', or colloquially as ''teabagging''. It may be performed by a sexual partner as foreplay before other human sexual activity, sexual activities, such as sexual intercourse, vaginal or anal sex, anal intercourse, or as an Eroticism, erotic and physical intimacy, physically intimate act of its own. Fellatio creates a risk of contracting sexually transmitted infections (STIs), but the risk is significantly lower than that of vaginal or anal sex, especially for HIV transmission. Most countries do not have laws banning the practice of fellatio, though some cultures may consider it taboo. People may also refrain from engaging in fellatio due to personal preference, negative feelings, or sexual inhibitions. Commonly, people do not view oral ...

Vanilla Sex
Conventional sex, colloquially known as vanilla sex, is sexual behavior that is within the range of normality for a culture or subculture, and typically involves sex which does not include elements of BDSM, kink, fetishism, and/or happens within a marriage or relationship. Etymology Early entries for ''vanilla'' in the ''Oxford English Dictionary'' refer to its botanical origins, such as the pod of the ''Vanilla'' genus or the orchid ''Vanilla planifolia.'' These definitions appeared in English texts as early as the 1600s. The figurative meaning—"plain, basic, or conventional"—was added in the 1970s, though earlier examples exist. A notable early instance appears in a 1942 ''LIFE'' magazine article, suggesting the metaphorical use was already familiar to the public. In 1997, the OED expanded the definition to include sexual contexts, particularly "vanilla sex," referring to conventional, non-kinky activity. Several citations stem from 1970s gay and lesbian discourse, coinc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
