Not if you have a fresh pair in a bag nearby. Do people actually go back home with sandy underwear?
I have a friend who wears them, will shower in his underwear, then changes out the underwear for a different pair when leaving. It's like what the point. Just put on your board shorts and go swim.
I can't imagine wearing underwear under my swimming shorts... It's weird. I even don't like to wear shorts at the beach, thats why we go to nudist beaches, but shorts+underwear? What is the point of that?
I swim with underwear. Who knows if your shorts are gonna fall off
My shorts actually fell off once when I jumped in the pool and I swam in then picked it up, it was normal hence most people here were briefs or boxer-briefs under their swimming shorts
