Naked scuba diving and mass skinny-dipping
If watersports are more to your taste, why not give naked scuba diving a go? Sea lice can get trapped under clothes but are unable to hold on to naked skin, so it's safer than using a wetsuit but there are nonetheless a couple of safety issues to bear in mind. Body hair can be an issue so the hirsute should shave; more worryingly, fish cannot always tell the difference between a man's tackle and genuine fish food so wear trunks if you don't fancy baiting the aquatic inhabitants.
A host of resorts offer naked scuba diving including the Eden Bay Caliente resort, in the Dominican Republic, and the Hidden Beach Resort, in Playa del Carmen, Mexico. Alternatively, if you prefer an even freer kind of diving, head to the US city of Baltimore on 10 July for a world record attempt on the largest ever skinny-dip.
