Being nude in nature should be a more common and accepted thing. Ive camped, off roaded, done a little bouldering, boated, hiked and climbed trees nakey; solo and with other bros and girls. Personally, I think its one of the most effecient methods of bonding with other like minded individuals and being at one with nature. While out in the buff Ive even taken pics of others and had others take pics of me; male and female. Its not really a big deal. When done with peers, it is perhaps, one of the most liberating experiences of ones life. Arousal has never been an issue, like some guys in the pics above, and i imagine itd be tough, if not dangerous trying to hike around with that thing bouncin all around high fiving everything that gets close. Ha. It all depends on the surroundings, of course. Definitely have had a mosquito bite on my dick, lol, and that, guys, would have to be the worst thing i can think of thats ever happened.
