Maybe you do not know that nakednnes is another step from Sexual freedom. During the day of your father’s sex was not rampant. Sex was accorded respect but virtually everyone is having sex now. If you are not having it, you are watching it, singing it or making jokes about it so displaying a body can no longer be a big deal when opening body for sex is no longer that ….and by the way shes not naked. She’s wearing an appropriate piece for swimming. Or do you expect her to r suit?
