Do all boys feel the need to show off?

my brothers at times will walk through the house naked either to and from the shower and bedroom or to the kitchen for something to eat. and it seems like when my dad is not home

i know its hot out and humid and we have no ac.

i been at my friends house and their brothers do the same thing...🤔🤔🤔
