I had no “cultural shock” in the military or sunbathing along a river in Germany when my son as stationed there. My sister-in-law, on a visit to the base once, came along with us to the river (we were not nude). I was concerned about her seeing “jiggly bits.” When we came across several men nude, I asked if she wanted to go back. “No,” she quickly said. “I don’t get to see this every day!” We continued our hike, enjoying nature!
