Many pools in Belgium prohibit the use of swimming shorts, citing hygienic concerns with people concealing their underwear beneath them as well as safety concerns with them getting hooked on protrusions and the like. The main alternative is Speedo-like swimming briefs, but I feel naked and insecure in them. This is the biggest reason why I haven't been in any swimming pool in about a decade, back during my puberty.
Since it's that long ago since I have last been in a public pool, none of my swimwear fits me anymore, so I need to buy new. However, I don't want to wear briefs because as mentioned above, I feel very uncomfortable in them.
I checked some websites, and http://www.artofmanliness.com/2014/07/22/swim-suit-men/ mentions the most prevalent options. Of those, trunks, board-shorts and swim briefs are right out. the other options give more coverage and would likely make me feel less naked. In fact, I would prefer to wear a wetsuit wherever possible, but I'm not sure whether most swimming pools even accept those, since they might cite the hygienic concerns they have with swimming shorts.
Are wetsuits accepted in Belgian and Western European swimming pools? or should I look for another option?
I want to clarify that it's not attracting attention that I'm concerned about (as most people have assumed in their answers and comments). I'm concerned about running around in a small piece of fabric that covers very little, more specifically a speedo-style pair of briefs, and is quite easily depantsable (although that's not as much of a risk anymore in my mid-twenties). Being nearly depantsed as a teen by a trio of teen girls in a crowded pool is not that healthy for nakedness insecurities...
