People looking for anonymous sex are said to be "cruising for sex." Often this occurs in places where such an activity is common, such as sex clubs, bathhouses, and certain websites.
Anonymous sex is considered a form of prostitution if money or drugs are exchanged for sexual interaction. Similarly, utilizing the services of a recognized prostitute may also be considered anonymous sex.
Some people are attracted to the rush of anonymous sex, and many participants feel they lose their inhibitions in this type of encounter. However, anonymous sex is a very high risk activity, as there’s no way of knowing the sexual history of the other participant or participants. People who engage in anonymous sex typically have a greater number of sexual partners than other members of the population, so they also pose a greater risk of carrying sexually transmitted infections.
