According to the article:
Girls are keeping up with boys on college spring break trips, although many later regret being a "girl gone wild." In another AMA study, 40% of the girls who went on such trips said they do not remember part of it because they were either drunk or passed out, 13% said they had sex with more than one partner, and 10% now regret engaging in public or group sex on the trip.
That means that 87% of girls go on Spring Break and only fuck one guy instead of several, and 90% never manage to fuck in public or with a group. What the hell is wrong with those girls? Maybe they went to the wrong place? I would demand my money back from whatever tour company sold me the tickets if I was them.
