I don't think any of the guys have anything to be too hung up about. When I was much younger and swam in college, I had a nice chest and abs that just seemed to come with not much effort. I kept most of that into my late thirties, albeit slowly the definition became a bit less clear. Now, as an older swimmer, I am happy to have a nice flat stomach and fairly well defined pecs, but gravity and age certainly take their toll. While ladies have all the pressure to look pretty, guys put lots of pressure on themselves to look masculine and strong. I agree with Sebbie that if it helps us to stay healthy and fit, great. Life is too short to be obsessive, however. I say, put on a cute swimsuit, enjoy the beach, and don't worry if someone gets hung up because you aren't Adonis in a Speedo (or whatever you choose to wear!).
