Gotta love the feeling of a one piece. I really only like the high-neck back-zip style, not so much the step-in strappy ones. Trisuits are available in both mens and womens styles, sometimes they sell them as UV protective or sun suits, or as a rashguard suit for wearing under wetsuits. I've gone swimming at the gym wearing a black high-neck wrestling singlet. It's hard to tell if you're getting a negative reaction from people (or if they even notice) when you're so excited and self-conscious at the same time. I guess that's part of the fun.
Lately I picked up an Adidas squat suit that I've been wearing as a swimsuit (only in a private pool so far). I admittedly don't have the hottest legs at the moment so I like the longer leg length, but this style has the benefit of giving the illusion that I'm wearing a leotard over shorts.
Can't find a pic on the web, so I guess I'll have to post one of my own
Since it hasn't been mentioned, there is a site dedicated to men in one piece swimsuits at:
