identities and freedom to explore their sexualities. Data from 2007 to 2017 indicates that there has been a decline in casual sex among young adults. A 2021 study attributed the decline to reduced alcohol consumption, increased video gaming, and a larger share of young adults living with their parents. Impact of COVID-19 Casual sex is a high-risk activity during COVID-19 and research has shown that many people are limiting contact with sexual partners outside their social bubbles. When public health guidelines exist, the suggestions are fairly consistent: ‘solo sex’ and sex with a housemate (spouse, roommate, etc.) are safest and masks and disinfection (hand washing, shower, etc.) are essential for sex with a partner outside one's social bubble. Prevalence and norms A study in 2019 found that 23% to 33% of women surveyed dated men for a free meal termed "foodie call". Colleges Research suggests that as many as two thirds to three quarters of American students have casual sex at least once during college. On college campuses, casual sex may occur almost anywhere. The majority of hookups happen at parties. Other common casual sex venues are dorms, frat houses, bars, dance clubs, cars, and public places or wherever is available at the time. Collegiate holidays and vacations, especially spring breaks, are times that undergraduates are more likely to purposely seek out casual sexual encounters and experiment with risky behaviors. This is due to the availability of alcohol and uninhibitedness of spring break venues. One study reported that about 30% of collegiate spring breakers, whether they are in a monogamous relationship or not, have penetrative sex with a person they meet during their break. A 1995 study of Canadian students who had traveled to Florida for spring break, found the key elements of a spring break vacation to include a group holiday with friends traveling and rooming together, a perpetual party atmosphere, high alcohol consumption, sexually-suggestive contests and displays, and the perception that casual sex is common. Overall, there was a perception that sexual norms are far more permissive on spring break vacation than at home, providing an atmosphere of greater sexual freedom and the opportunity for engaging in new sexual experiences. Of the 681 students who completed a questionnaire after the break, 15% of males and 13% of females had engaged in casual sex during the break. Nearly 61% of men and 34% of women who had casual sex
