How do you get comfortable sunbathing in the nude?

I'm a very open person and I don't think there is anything wrong with sunbathing in the nude. The only problem is, I live in America and our country tends to make us feel ashamed of our bodies. I like the European way of thinking when it comes to their bodies, especially countries like Greece. They don't see the naked body as something ual all the time or something to be embarred about, and they are comfortable being nude even around family members of the opposite . I like that, how they can do that without making a big deal out of it and making it seem ual (especially being around a family member of the opposite because too many people in my country would say it's ual and that is just disgusting and immature). I want to be able to think that way, but how? I'm planning on going to a nude beach that is for women only with a couple of girlfriends to start feeling free and liberated and not ashamed of my body, but I am still very shy about my body and it's hard to stop being a bit embarred and shy about my body because that is how my society has taught me to think and behave. So how can I embrace myself more and take that plunge?
