When the sun is shining, you can sit naked on the saddle of your bike in the great outdoors - in certain places - and enjoy the area. My ass loves the feeling of the hard saddle, the perineum rubbing against it and parts my fat scrotum. The glans of the penis has retreated into the foreskin - because the wind is a bit fresh. On the bumpy dirt road I sometimes stand up and let my genitals wobble nicely. I love the feeling of freedom and enjoy being naked in nature - unfortunately not always possible.
