You will never look back. I have worn brief swimsuits at the beach (or anywhere) as long as I can remember, and even in HS when I was almost always the only guy who did (even my fellow swim team guys did not, except for my best friend Zach). You'll look awesome and feel great, and should you get a little aroused there is a whole ocean to cool off in, although a little arousal only adds to the experience. Enjoy, and let us know how it works out.
