Coital
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. There a ...

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 ...

Anal Sex
Anal sex or anal intercourse is generally the insertion and thrusting of the erect penis into a person's anus, or anus and rectum, for sexual pleasure.Sepages 270–271for anal sex information, anpage 118for information about the clitoris. Other forms of anal sex include fingering, the use of sex toys for anal penetration, oral sex performed on the anus ( anilingus), and pegging. Although ''anal sex'' most commonly means penileanal penetration, sources sometimes use ''anal intercourse'' to exclusively denote penileanal penetration, and ''anal sex'' to denote any form of anal sexual activity, especially between pairings as opposed to anal masturbation. While anal sex is commonly associated with male homosexuality, research shows that not all gay men engage in anal sex and that it is not uncommon in heterosexual relationships. Types of anal sex can also be a part of lesbian sexual practices. People may experience pleasure from anal sex by stimulation of the anal nerve e ...

Human Sexual Activity
Human sexual activity, human sexual practice or human sexual behaviour is the manner in which humans experience and express their sexuality. People engage in a variety of sexual acts, ranging from activities done alone (e.g., masturbation) to acts with another person (e.g., sexual intercourse, non-penetrative sex, oral sex, etc.) in varying patterns of frequency, for a wide variety of reasons. Sexual activity usually results in sexual arousal and physiological changes in the aroused person, some of which are pronounced while others are more subtle. Sexual activity may also include conduct and activities which are intended to arouse the sexual interest of another or enhance the sex life of another, such as strategies to find or attract partners (courtship and display behaviour), or personal interactions between individuals (for instance, foreplay or BDSM). Sexual activity may follow sexual arousal. Human sexual activity has sociological, cognitive, emotional, behavioural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oral Sex
Oral sex, sometimes referred to as oral intercourse, is sexual activity involving the stimulation of the genitalia of a person by another person using the mouth (including the lips, tongue, or teeth) and the throat. Cunnilingus is oral sex performed on the vulva or vagina, while fellatio is oral sex performed on the penis. Anilingus, another form of oral sex, is oral stimulation of the anus. Oral sex may be performed as foreplay to incite sexual arousal before other sexual activities (such as vaginal or anal intercourse), or as an erotic and physically intimate act in its own right. Like most forms of sexual activity, oral sex can pose a risk for contracting sexually transmitted infections (STIs/STDs). However, the transmission risk for oral sex, especially HIV transmission, is significantly lower than for vaginal or anal sex. Oral sex is often regarded as taboo, but most countries do not have laws which ban the practice. Commonly, people do not regard oral sex as affectin ...

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 ...

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] |
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] |
Physical Intimacy
Physical intimacy is sensual proximity or touching. It is an act or reaction, such as an expression of feelings (including close friendship, platonic love, romantic love or sexual attraction), between people. Examples of physical intimacy include being inside someone's personal space, holding hands, hugging, kissing, caressing and sexual activity. Physical intimacy can often convey the real meaning or intention of an interaction in a way that accompanying speech cannot do. Physical intimacy can be exchanged between any people but as it is often used to communicate positive and intimate feelings, it most often occurs in people who have a preexisting relationship, whether familial, platonic or romantic, with romantic relationships having increased physical intimacy. Several forms of romantic touch have been noted including holding hands, hugging, kissing, cuddling, as well as caressing and massaging. Physical affection is highly correlated with overall relationship and partner ... [...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 ...
