There's a freedom in shedding the material you cover your body with, and allowing the sun to bathe parts of you it's usually hidden from.
No matter your gender or age, do a hand-or-headstand and spread yours legs in the sky. I'm serious... It's similar to swimming naked in the ocean (also something I highly recommend doing).
You'll recognize the exhilarating feeling from childhood when the human body & freedom of expression, weren't immediately judged, sexualized, or shamed.
They call it where the sun don't shine... Is it a reminder that the sun has a more difficult time reaching those areas, and that we should let it shine down there more often..
The entire body craves the sun's rays. So let it shine on every corner and crevice of your beautifully free body.
That includes between the cheeks, under the balls & tits, right on the nips, and even the armpits.
