My father was never shameful. He loved being naked in front of me. I remember the first moments we talked about hygiene in private parts. Any too?My dad and I were always nude at home, no shame ever existed in our home. We had several nudist dad and sons friends who often joined us. We had a very large shower that had several shower heads. We always enjoyed soaping up each other making sure that we got all the nooks and crannies. Dads washed different nudist sons and sons washed different nudist dads. It really was a great way to enjoy nude bonding.
I've had a similar past. Growing up, being nude at home was considered very normal for the men in the family. But nobody knew about nudism being a thing until I grew up and found out about it much later. Dad and I were never shy around each other. We still have those moments of being naked together when I visit his place. Best way to get rid of barriers!
