Should there be 3 types of locker rooms/changing rooms?

Obviously there’s the 2 main locker rooms for men and women but should a third locker room exist. The third one could be for boys and girls under a certain age of either 16 or 18 and also younger children can be supervised by a parent. I feel like if a young teen boy is with their friends at the swimming pool or beach and they are showering naked after they are finished some wouldn’t want to be seen/seeing older naked guys. It might be better for all younger people to be seperated and put together with only limited adults allowed in (mostly a responsible parent with a young child). I’m a 16 year old boy and I would probably feel more comfortable in a mixed changing room or showers with girls and boys my age then older guys.
