I just got lucky and found the original article including the comment about oral:
""Canadian women are mostly in Barbados now, which is somewhat upmarket; Jamaica is poorer," Belliveau said. "And the Dominican is slowly getting the reputation of having men that are very eager to be the world’s best lovers. In the French islands, the men are more suave and gallant and won’t accept payment."
But sex with the locals isn’t without drawbacks or controversy.
The most obvious is money: according to a couple of studies in Jamaica, it can cost $20 to $30 for an hour of sex, or $150 for a full night that includes oral sex (usually seen as demeaning by the island men). Second, some tourist women have reported that Caribbean lovers are over-rated, dulled by drink or dope; others can be chauvinistic, domineering, even violent.
Then there’s the issue of the social impact of the sex trade. It affects ordinary tourists, who complain of harassment. It affects young mothers, who complain of the men not being around to provide for their children. Island women can also act hostile toward white vacationers, seeing them as home wreckers."
