It's fun to watch this guy struggle to get into a really snug-fitting suit, white gloves and all. He is wearing a black Speedo brief under "for purposes of the video only". In a real locker room he would be nude doing this.
I keep thinking of a hypothetical xtube video showing 6 or 8 competitive swimmers in a locker room all getting into their fastskin suits. I wonder how their male anatomies would "react" to all the ruckus going on!
