Nudity and Comfort Level in Public

Im curious to see everyone's comfort level with nudity. I'm from the states and moved to Germany. I'm surprised with myself how uncomfortable I get with nudity here... Husband is German and it's no big deal to him. He would easily tan nude on a crowded beach with his whole fam. His mom and sister tan topless in the backyard. They came to the states and found a nude beach. I went once to a nude beach and this man was standing by the water with a complete hard on, he didn't seem to mind haha

Please answer and share thoughts/stories if you wish :-)
