This article concentrates on physical activity. Social and psychological issues are covered in other, related articles such as heterosexuality and homosexuality.
There is no clear borderline between sexual and nonsexual enjoyment of touching someone else's body. For example, holding hands may or may not have a sexual connotation, depending on culture, situation and other factors. There are, however, actions that are clearly sexual by almost anyone's definition but which have been argued by an accused as not having sexual relations since the most common form of heterosexual sexual intercourse had not occurred. The distinction between sexual and nonsexual behavior can be relevant due to social rules.
Some criteria that may be applied are:
While enjoying touching the body of someone else implies enjoying one's own body also, the latter may also happen without another person; enjoying one's own body also may or may not be of a sexual nature. If it is, it is called autoeroticism.
The whole of one's sexual activities (including erotic and wet dreams and waking sexual fantasies and daydreams) is called one's sex life.
Sexual desire or libido is the desire for sexual behavior. Most people focus their sexual desire on someone that they have a sexual relationship with, or would desire to have a sexual relationship with. See also sexual arousal, sexual orientationSexual orientation, sexual preference or sexual inclination describes the focus of a person's amorous or erotic desires, fantasies, and feelings. A person's sexual orientation is most often classified by the gender(s) one is "oriented" towards, as: hetero.
Many people enjoy fantasizing about, or reading or viewing depictions of, sexual fantasies of activities that they do not wish to engage in in their own lives, or that they would be unable to engage in in their own lives; see pornography and erotica.
Opinions and normThe word norm coming from the latin word norma which means " angle measure" or (lawlike) "rule", has a number of meanings: A social or sociological norm, see norm (sociology). A principle of right action, see normative. A statistical concept in psychometrs vary about whether an emotional bond of a certain intensity and durability should be a prerequisite for sex (see also below).
Like other primateFor the ecclesiastical use of this term, see primate (religion 13, See text A primate is any member of the biological order Primates the group that contains all lemurs, monkeys, and apes, including humans. The English singular primate is a back-formations, Homo sapiens use sexuality for reproduction and for maintenance of social bonds. It is generally acknowledged that children are capable of feeling sexual pleasure, even if they are not yet able to engage in sexual intercourse with each other, and/or are not yet biologically able to reproduce. Yet, child sexuality has historically been severely limited in western societies; in the late 19th century, the hysteria surrounding so-called "self-abuse" ( masturbation) among children reached its peak and fueled the adoption of circumcision (including female circumcision) in some cultures.
Many sexual activities can be engaged in by same sex or opposite sex partners. However some, most notably vaginal sexual intercourse, can only be engaged in by partners of opposite sexes. And others, such as tribadism and "swordfighting" can only be engaged in by partners of the same sex.
As with other behaviors, our high intelligence and complex societies have produced in us the most complicated sexual behaviors of any animal. Most people experiment with a range of sexual activities during their lives, though they tend to engage in only a few of these regularly. Most people enjoy some sexual activities. However, most societies have defined some sexual activities as inappropriate (wrong person, wrong activity, wrong time, etc.) Some people enjoy many different sexual activities, while others avoid sexual activities altogether for religious or other reasons (see chastity, sexual abstinence, asexuality). Historically, most societies and religions have viewed sex as appropriate only within marriage. There is still a widespread belief that sex acts are devalued when engaged in outside of a long-term, monogamous romantic relationship, but extra-marital sexual activity and casual sex became increasingly accepted in modern society during the sexual revolution.
