Speedo swimsuits on men are pretty much universally awful. My three year old wanted to know why a man was only wearing women's underwear to swim in. I think that says enough.

If, despite contempt and ridicule even from the mouths of short little blonde girls, a man persists upon wanting to wear this disgusting form of swimwear, please make sure that you can at least fill it out. Leaving nothing to the imagination in a Speedo is bad enough. If you are too small to fit in a tight fitting lycra suit (before getting in the cool water) I really, really don't need to know about it.
