Dominican Republic hands down without a question. I went with 3 guys a few years ago. They have great beaches, nightclubs , strip clubs, casinos... Anything goes. And American guys are superstars with the chicas....just don't wear too much jewelry and you are good to go.
Dominican chicks aren't shy. They will come right up to you and flirt if they are into you. And I don't mean the pros. The regular civilian chicks
