What's wrong with Americans and speedos??....Growing up in Italy I got used to see speedos in any kind of man, muscular, skinny, normal, gorgeous or fat and ugly. Whatever you wear doesn't change who you are. At the beach wear whatever you feel more comfortable with. I live close to Brighton Beach in Brooklyn and go there often in summertime, it's absolutely refreshing and liberatory to see how most men (only Russians...) don't give a shit if they don't have a perfect body, but want to enjoy comfort on a beach.
Those ridiculous shorts/trunks that most men use are hideous, unless it's what you WANT to wear. To me they are totally uncomfortable at the beach. I have passed 50 4 years ago, I have a more than decent body and even if I didn't I would not care. I wear speedos always because I like it. If I am not in Miami Beach or in Brighton Beach I am usually one of the VERY few who wear speedos, and I don't give a damn if people are "offended" by the view of a bulge or my wrapped buttocks. People in US are super comfortable with violence, but body and sex (remember Janet Jackson's nipple?...) are taboo. Wrooong!
