Fresh air
I would recommend this pose for everyone, male or female, whether on the beach or in the privacy of your home. It allows areas that tend to remain hot and sweaty to air out and dry. This combats bacteria and fungus growth.
Hate to be that guy, but tanning your genitals isn't the greatest idea as they're naturally more sensitive and prone to sunburn.
Well said. ALWAYS use sunscreen.
A beautiful sight to behold. I agree this pose should be encouraged.
