Religious views on sexuality vary significantly between different religions and sects of the same religion, though there are common themes, such as prohibition of adultery. Reproductive sexual intercourse between non human animals is more often termed copulation, and sperm may be introduced into the females reproductive tract in non vaginal ways among the animals, such as by cloacal copulation. For most non human mammals, mating and copulation occur at the point of estrus the most fertile period of time in the females reproductive cycle, which increases the chances of successful impregnation. However, bonobos, dolphins and chimpanzees are known to engage in sexual intercourse regardless of whether or not the female is in estrus, and to engage in sex acts with same sex partners.

The age of first sexual intercourse is called sexarche. Vaginal, anal and oral sex are recognized as sexual intercourse more often than other sexual behaviors.

Virginity loss is often based on penilevaginal intercourse partly because heterosexual couples may engage in anal or oral sex not only for sexual pleasure, but as ways of maintaining that they are virgins if they have not engaged in the reproductive act of coitus. Similarly, some gay men consider frotting or oral sex as ways of maintaining their virginities, with penile anal penetration defined as sexual intercourse and resulting in virginity loss, while other gay men may define frotting or oral sex as their main forms of sexual activity. Lesbians may define oral sex or fingering as sexual intercourse and subsequently an act of virginity loss,91. Researchers commonly define sexual intercourse as penilevaginal intercourse while using specific terms, such as anal sex or oral sex, for other sexual behaviors. Scholars Richard M. Lerner and Laurence Steinberg state that researchers also rarely disclose how they define sex or even whether they resolved potential discrepancies in definitions of sex. Learner and Steinberg attribute researchers focus on penilevaginal sex to the larger cultures preoccupation with this form of sexual activity, and have expressed concern that the widespread, unquestioned equation of penilevaginal intercourse with sex reflects a failure to examine systematically whether the respondents understanding of the question about sexual activity matches what the researcher had in mind. This focus can also relegate other forms of mutual sexual activity to foreplay or contribute to them not being regarded as real sex, and limits how rape is defined. It may also be that conceptually conflating sexual activity with vaginal intercourse and sexual function hinders and limits information about sexual behavior that non heterosexual people may be engaging in, or information about heterosexuals who may be engaging in nonvaginal sexual activity.
