I’m not going to say you’re wrong or that you didn’t look well enough. I get told that myself a lot when I complain that men’s options are always way more limited than women’s. But I’m slowly finding men’s clothing brands for myself, including beach stuff. Those
graphic swim trunks for men are often made from light fabrics that dry fast and don’t irritate the skin. The fit is also pretty good, and I like that there are some bright color options. So through a long search I’m gradually finding some stores where I buy things from time to time.
