Most young adults in this age group believe that their peers are having a higher frequency of casual sex than they actually are, and this is due to vocabulary choice. For example, using the term "hookup" denotes that the sexual activity, whether it is vaginal sex, oral sex, or sexual touching, is casual and between unfamiliar partners. However, it is vague and does not detail what specific sexual activities occurred. This is especially distorting towards others' impressions because 98% of college hookups involve kissing, 81% of hookups involve more than kissing, and only 34% of hookups involve penetrative sex. Studies have also linked this common misperception of peer hookup activity to media and pop culture portrayals of casual sexual encounters. Television and movies project distorted depictions of casual sex because they also commonly portray people who have just hooked up as emotionally satisfied and physically pleasured while simultaneously emotionally detached, which is not always the case. According to a 2004 peer-reviewed study published in the Journal of Marriage and Family found that women who have more than one premarital sexual relationship have a higher likelihood in the long run of disruptions if ever married, with this effect being the "strongest for women who have multiple premarital coresidential unions". Kahn and London (1991) found that premarital sex and divorce are positively correlated. Legal and religious issues Attitudes to casual sex range from conservative and religious views, the extreme of which may result in imprisonment or even capital punishment for sexual relations outside heterosexual marriage, to liberal (libertarian or libertine) views, the extreme of which is free love. Legal The legality of adultery and prostitution varies around the world. In some countries there are laws which prohibit or restrict casual sex. In some Muslim-majority countries, such as Saudi Arabia, Pakistan, Afghanistan, Iran, Kuwait, Malaysia, Morocco, Oman, Mauritania, United Arab Emirates, Sudan, and Yemen, any form of sexual activity outside marriage is illegal. Religious views Most religions disapprove of sex outside marriage (see religion and sexuality), and the consequences range from very serious to none. Also, marriage is defined in quite different ways in different cultures, for example, with "short-term marriage" (see Nikah mut'ah) a cover for prostitution, or polygamy. Although some religious
