Philly, wrong, we have been to Europe as well as other areas where even total nudity while sunning and swimming is no big deal. Point was that many families do not appreciate thongs onboard ships which was the question, not if they are acceptable in other countries. Yes it is more common and more acceptable on a fit young lady than an overwieght one. Not hard to figure that out. <G> Overweight or not, it is not accepted by hardly anyone for a male to wear one onboard a ship. Again, I would not want my pre-teen daughter, (I don't have one BTW), to get an anatomy lesson from some old dude with a string thong on, it is pretty disgusting IMHO as well as those I know, both male and female.
