Welcome ashore Those are VERY GOOD questions.. Its because of the way they were brought up (One reason anyway)
Can people overcome the feeling that the natural human condition is inherently grotesque, inherently sexual, inherently indecent? Some people can get past these attitudes and in a surprisingly short time. For those who succeed in deprogramming the body issues, there are several rewards: Living the way the body was designed, nude, it's healthier in mild weather! Raising your kids without body hangups and lechery. Accepting the bodies of others, young and old, fit and fat, beautiful and plain. The chance to create a more open, egalitarian society. The sheer physical pleasure of enjoying sun and mist, fresh air all over. Clothing is a form of sensory deprivation. It is a powerful but pleasant shock when you restore the sense of touch to your entire body!
If they are real friends they will accept you and your lifestyle even if it does not suit their own lifestyle! A lot of our friends know we nudists and don't have an issue, it's not something they want to do but accept us as nudists.
