Many people have been brought up taught that nudity is immoral and we should never allow others to see our true bodies. It is alright to titillate with provocative clothing, or tiny beach wear, but not to show the natural beauty of our bodies, especially genitals or women's breasts. This sense of shame is not inborn: it is learned. Babies have no shame and neither did many early Christians in Biblical times. Fortunately today there is also a very rapidly growing naturist movement that has learned: "Nude is not lewd"
