Copulatory
Sexual intercourse (or coitus or copulation) is a sexual activity typically involving the insertion and thrusting of the penis into the vagina for sexual pleasure or reproduction.Sexual intercourse most commonly means penile–vaginal penetration for sexual pleasure or sexual reproduction; dictionary sources state that it especially means this, and scholarly sources over the years agree. See, for example; * * * * * * * * * This is also known as vaginal intercourse or vaginal sex. Other forms of penetrative sexual intercourse include anal sex (penetration of the anus by the penis), oral sex (penetration of the mouth by the penis or oral penetration of the female genitalia), fingering (sexual penetration by the fingers) and penetration by use of a dildo (especially a strap-on dildo). These activities involve physical intimacy between two or more individuals and are usually used among humans solely for physical or emotional pleasure and can contribute to human bonding.

Animal Sexual Behaviour
Animal sexual behaviour takes many different forms, including within the same species. Common mating or Reproduction, reproductively motivated systems include Monogamous pairing in animals, monogamy, Polygyny in animals, polygyny, Polyandry in nature, polyandry, polygamy and promiscuity. Other sexual behaviour may be reproductively motivated (e.g. Sexual coercion among animals, sex apparently due to duress or coercion and situational sexual behaviour) or Non-reproductive sexual behavior in animals, non-reproductively motivated (e.g. Homosexual behavior in animals, homosexual sexual behaviour, bisexuality, bisexual sexual behaviour, cross-species sex, Paraphilia, sexual arousal from objects or places, Necrophilia in animals, sex with dead animals, etc.). When animal sexual behaviour is reproductively motivated, it is often termed ''mating'' or ''Copulation (zoology), copulation''; for most non-human mammals, mating and copulation occur at Estrous cycle, oestrus (the most ferti ...

Penis
A penis (plural ''penises'' or ''penes'' () is the primary sexual organ that male animals use to inseminate females (or hermaphrodites) during copulation. Such organs occur in many animals, both vertebrate and invertebrate, but males do not bear a penis in every animal species, and in those species in which the male does bear a so-called penis, the penises in the various species are not necessarily homologous. The term ''penis'' applies to many intromittent organs, but not to all. As an example, the intromittent organ of most cephalopoda is the hectocotylus, a specialized arm, and male spiders use their pedipalps. Even within the Vertebrata there are morphological variants with specific terminology, such as Hemipenis, hemipenes. In most species of animals in which there is an organ that might reasonably be described as a penis, it has no major function other than intromission, or at least conveying the sperm to the female, but in the Eutheria, placental mammals the peni ...

Vagina
In mammals, the vagina is the elastic, muscular part of the female genital tract. In humans, it extends from the vestibule to the cervix. The outer vaginal opening is normally partly covered by a thin layer of mucosal tissue called the hymen. At the deep end, the cervix (neck of the uterus) bulges into the vagina. The vagina allows for sexual intercourse and birth. It also channels menstrual flow, which occurs in humans and closely related primates as part of the menstrual cycle. Although research on the vagina is especially lacking for different animals, its location, structure and size are documented as varying among species. Female mammals usually have two external openings in the vulva; these are the urethral opening for the urinary tract and the vaginal opening for the genital tract. This is different from male mammals, who usually have a single urethral opening for both urination and reproduction. The vaginal opening is much larger than the nearby urethral opening, an ...

Sexual Stimulation
Sexual stimulation is any stimulation, stimulus (including bodily contact) that leads to, enhances and maintains sexual arousal, and may lead to orgasm. Although sexual arousal may arise without physical stimulation, achieving orgasm usually requires physical sexual stimulation. The term ''sexual stimulation'' often implies stimulation of the sex organ, genitals, but may also include stimulation of other areas of the body, stimulation of the senses (such as sight or hearing) and mental stimulation (i.e. from reading or sexual fantasy, fantasizing). Sufficient stimulation of the human penis, penis or clitoris usually results in an orgasm. Stimulation can be by self (e.g., masturbation) or by a sexual partner (sexual intercourse or other Human sexual activity, sexual activity), by use of objects or tools, or by some combination of these methods. Some people practice Edging (sexual practice), orgasm control, whereby a person or their sexual partner controls the level of sexual stimu ...

Pelvic Thrust
The pelvic thrust is the thrusting motion of the pelvic region, which is used for a variety of activities, such as dance or sexual activity. Sexual activity The pelvic thrust is used during copulation by many species of mammals, including humans, or for other sexual activities (such as non-penetrative sex). In 2007, German scientists noted that female monkeys could increase the vigor and amount of pelvic thrusts made by the male by shouting during intercourse. In whitetail deer, copulation consists of a single pelvic thrust. Dance One of the first to perform this move on stage was Elvis Presley. It was quite controversial due to its obvious sexual connotations. Due to this controversy, he was sometimes shown (as seen on his third appearance on ''The Ed Sullivan Show'') from the waist up on TV. Later, the pelvic thrust also became one of the signature moves of Michael Jackson. Twerking, a reverse and sometimes passive form of pelvic thrust dance move, is also a very popular ...

Sex Organ
A sex organ (or reproductive organ) is any part of an animal or plant that is involved in sexual reproduction. The reproductive organs together constitute the reproductive system. In animals, the testis in the male, and the ovary in the female, are called the ''primary sex organs''. All others are called ''secondary sex organs'', divided between the external sex organs—the genitals or external genitalia, visible at birth in both sexes—and the internal sex organs. Mosses, ferns, and some similar plants have gametangia for reproductive organs, which are part of the gametophyte. The flowers of flowering plants produce pollen and egg cells, but the sex organs themselves are inside the gametophytes within the pollen and the ovule. Coniferous plants likewise produce their sexually reproductive structures within the gametophytes contained within the cones and pollen. The cones and pollen are not themselves sexual organs. Terminology The ''primary sex organs'' are the gonads, a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fingering (sexual Act)
Fingering is typically the use of fingers or hands to sexually stimulate the vulva (including the clitoris) or vagina. Vaginal fingering is legally and medically called digital penetration or digital penetration of the vagina. Fingering may also include the use of fingers to sexually stimulate the anus. Fingering may be performed on oneself (masturbation) or by or with a sexual partner. When performed on the vulva or vagina by a sexual partner, it is a form of mutual masturbation, and is analogous to a handjob (the manual stimulation of the penis). It may be used for sexual arousal or foreplay, constitute an entire sexual encounter, or be used as a form of non-penetrative sexual activity. Stimulation Vulva Parts of the vulva, especially the clitoris, are erogenous zones. * Massage of the vulva, and in particular the clitoris, is the most common way for a woman to achieve an orgasm. Studies indicate that 70-80% of women require direct clitoral stimulation to achieve orgasm. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dildo
A dildo is a sex toy, often explicitly phallic in appearance, intended for sexual penetration or other sexual activity during masturbation or with sex partners. Dildos can be made from a number of materials and shaped like an erect human penis. They are typically about the average length of an erect penis, , but some may be longer. A dildo's circumference is typically . Description and uses General A dildo is an object usually designed for sexual penetration of the vagina, mouth, or anus, and is usually solid and phallic in shape. Penis prosthetic aids, known as "extensions", are not considered dildos. Some include penis-shaped items clearly designed for vaginal penetration, even if they are not true approximations of a penis. An anal dildo is intended for repeated anal penetration, to be distinguished from a butt plug which is flanged with the intent of remaining in place. People of all genders and sexual orientations use these devices for masturbation or other sexual activ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strap-on Dildo
A strap-on dildo (also strap-on) is a dildo designed to be worn, usually with a harness, during sexual activity. Harnesses and dildos are made in a wide variety of styles, with variations in how the harness fits the wearer, how the dildo attaches to the harness, as well as various features intended to facilitate stimulation of the wearer or a sexual partner. Strap-on dildos are most frequently used by lesbian women (or women who have sex with women), but can be used by people of any gender or sexuality. A strap-on dildo can be used for a wide variety of sexual activities, including vaginal sex, anal sex, pegging, oral sex, or solo or mutual masturbation. Sexual lubricant can be used to ease insertion. Equipment Many types of equipment are available, with different features and drawbacks, for a strap-on dildo set up. Often the strap-on dildo will be used with a harness, but some do not need a harness or are built onto one; for these, please see the sections on dildo types a ...

Emotional Intimacy
Emotional intimacy is an aspect of interpersonal relationships that varies in intensity from one relationship to another and varies from one time to another, much like physical intimacy. Emotional intimacy involves a perception of closeness to another, sharing of personal feelings, and personal validation. Description Emotional intimacy can be expressed in verbal and non-verbal communication. The degree of comfort, effectiveness, and mutual experience of closeness might indicate emotional intimacy between individuals. Intimate communication is both expressed (e.g. talking) and implied (e.g. friends sitting close on a park bench in silence). Emotional intimacy depends primarily on the degree of closeness, as well as the nature of the relationship and the culture in which it is observed. Emotional intimacy is different from sexual intimacy in that sexual intimacy can take place with or without emotional intimacy. Sexual intimacy differs from emotional intimacy because the latte ...
