Ever see anyone who has no issues being naked but covers genitals with their hands? This is a common with younger people my age

I am 18 (almost 19) and while my generation may be more modest than past ones me and a lot of my friend are comfortable with nudity. We go to the k spa, occasionally skinny dipping no issues changing. The gym and sports complex we frequent has a good ratio of guys comfortable but I do notice the younger ones are actually comfortable naked in locker rooms and sauna many hold their hand over the gentils. Everything else wide exposed but gentials covered

During a recent trip to Atlanta with my dad and brother to a k

Spa seen the same thing. A lot of younger guys with no issues nude but still hand over down there.

Not criticizing at all. I feel it’s honestly a step in the right direction for body comfort but still a little odd
