If everyone was naked. In and outdoors.
I believe there be less, pedofiles. Less gays.
Emagine you were only 4 year old. At school. All you friends were naked as well. Plus the teachers.. Everyone would get used to the different sexes straight away. The parents would have to tell them about the birds and the bees. Lads would be able to see, girls Virginia+ tits. Girls would be able see lads penis. They would be able to choose which way they were going go as they were going to school. I believe that you would see more people biking understanding about others. Over time. There would be less lads going out with lads. Plus girls going out with girls.
If you could try nudity at home in front of your family. As well as at school. You would live a totally different way of life.
