It was never a sexually driven act to me it just feels right to set them free. My wife says she can see the outline of my cock in my shorts but I have not noticed anyone looking over the years.
One time on a particularly hot and humid day I looked down as my wife and I were sitting on a park bench and there was one of my testicles sitting in plain view of my short leg like a good friend with his own life. This of course gave us a good laugh and brought about the realization that this was now a possibility although it has not been a problem.
So how about it. How many men, and women for that matter are running about without underwear on and what are the reasons behind it. For me it just feels right kinda like sleeping naked. We have never owned pajama's but that is another story or two.
