What the hell is wrong with us? Why do we so enjoy being naked?

I find myself pondering why am I happy when Im naked. Why I am even happier around naked friends. What draws me to want to look a pictures of people naked people enjoying nude life? Do we get endorphins when we shed our clothes? Is it perversion or is it the erotic nature of the body? I for one have not been able to answer the why but the truth is I am happier when I am naked. Have you found the answer? Please share we us....
