You won't know what it's like to [visit a nudist colony] merely by looking at a picture of a bunch of naked people. The only way you'll know what it's like is if you get seen by a bunch of naked people. The only way to have the experience is to have the experience. Not by looking at the experience. By having it.
New experiences are scary, but the only way to have a new experience without cutting yourself off from the best part (which is the unique way you react to it) is to go get seen by a bunch of naked people yourself.
