Personally I would always wear something - my choice is generally a pair of swimming boxers. Just like wearing clothes I always prefer something between me and the outer layer - more hygienic and cover in the event of a split seam or similar.
I have invested in a changing robe as well - makes the removal of wet suit and wet boxers a lot less embarrassing at the roadside or on the boat. On a liveaboard, I would just towel reasonably dry and then head to the cabin for a shower wearing the shorts.
