[Tishabet]

I grew up in a similar context to what several of you are describing with your own children. My parents both slept naked, and there was nothing strange or embarassing about seeing them on their way to the shower in the morning or whatever. When I was young and we were all trying to get out the door at the same time for church, my mom and sister took one bathroom and the guys (me, my borther who is 9 years older, and my dad) took the other, "locker room" atmosphere, my dad tossing me a towel as I hopped out of the shower, etc. Also not uncommon for my dad to pee without closing the door, and in fact until I was around 7, we would often have "sword fights" where he and I would stand on opposite sides of the toilet and "duel" with our pee as we peed into the toilet. Sounds odd now, but was a lot of fun when I was growing up.
FWIW, neither of my parents would be labeled "hippy" or "liberal." Both have PhDs (mom in English, dad in Physics), both born and raised in the hard coal country of PA, and both attend church (Lutheran) every Sunday. My dad is a republican who graduated from West Point in 1962. The point is I'm now 25, I have a steady, healthy 3 year relationship with my girlfriend, my brother has been happily married for 12 years, and overall if I could change how I was raised in regards to nudity/the human body, I wouldn't. I think my siblings and I came out just fine.
