Celandina nailed it, but as someone who lives in a tourist town in JA I'd like to correct a few fallacies
first off, it's rent a dread, not rent a Rasta. men who practice the Rastafari faith do not engage in this. having dread locks does not make one a Rastafarian
also, it's not 'give me this much money for sex', it's much more informal. the woman pays for drinks and meals when they go out. he'll take her to local clubs and hang out spots, way different than the hotel ish. if a dude needs cash to fix his car, buy books for his kids for school, is behind on his rent, etc, the woman shells out the cash
aside from the companionship and sex, she gets to experience the real Jamaica, not the sanitized version experienced by the cruise ship passengers who get on buses to visit attractions strictly set up for them, where they par with other cruise ship passengers and listen to Bob Marley. I'm sorry, that is NOT the real Jamaica
so it's not a strictly pay for play thing. the women get far more than just sex. and the dudes are not real Rastas
also, no matter the nation, who
doesn't want to get laid on vacation?
re the OP's obsession with female age and weight, Jamaican men in general tend to prefer larger women. I'm slender but that's never stopped me from finding fun men to par with, but everyone is always trying to feed me
as to Tube Ace, we get it, you're the prettiest boy we ever did see. you trying to pick up here or something? go for Mature King, hear he's wild in bed
