There's two parts to modesty in the beach your own and those around you. You can't control those around you at the places where you go swimming, so it is just as important to avoid places where other people go, since they are all basically naked. For example, if you have a boat go out during the week or go to a sandbar where you are the only one. If on land go to a stream where no one goes. We go to those places and to beaches where few people go, and we set ourselves up far from others. If you take your glasses off you won't see those people far from you. As a man, I have no problem seeing the average women you see on the beach, older out of shape women, they are more of a sin against charity (scary sights!), though like I said I avoid places where there are people. If we are in a spot by ourselves, I don't have glasses on, and a young good looking naked girl ( girls in bikinis are naked) sets up next to us, I pack up the troops and move away or altogether leave the place.
