First of all, according to our female staff: Men pack ALOT 'bigger' package in Jamaica(sorry to be so blunt about it).
Maybe that's why 80,000 North American and European women flock to Jamaica for sex every year. Some of our own staff has admitted going there 2-3 times a year, (considering that some of these women are even married).
An estimated 650,000 Western women have engaged in travel sex from 1980 to the present, many of them as repeat customers.
"A holiday fling" or "a holiday romance" refer's to sex tourism. (having sex with a local) or an affair. Either may be called "fun in the sun". Euphemisms abound.
