You say you are a man and that you keep your shirt on. I don't know many men that swim with their shirts on but you have the right to keep yours on when you do. As for me, being a man, I choose to take mine off when I swim. I just wish my wife could if she so chose. You also told women to go to a nude beach if they want to take their tops off, I don't know where you live but the closest nude beach to where I live is several hundred miles away. Kind of far for a quick swim.
