I've been a closet Nudist for a number of years now ie around the house, but it was always on my own. I would love to try and be able to do the whole nude thing in public, but I'm a little embarrassed. Would anybody have some advice or tips for me.
You don't say where in public you intend to initiate yourself into open nudism, but I will assume for the minute that it's a beach or some other socially nude setting.
It's not unusual for a first timer to feel slightly embarrassed. But, that typically passes very quickly (with-in a few minutes time). In a socially nude setting, you will quickly see that "nobody stares, nobody cares". That helps any embarrassment pass very fast. Concentrate on how you feel being nude in the open and the freedom you will enjoy. That helps as well to take your mind off of any embarrassment. Behave as if you have been doing this forever. To act embarrassed only hightens the feeling.
Best advice I can give is to just do it. You will be glad you did.
