I don't know if it is something on the rise, but it does give me a rise to see someone jogging along and bouncing all over the place...especially a guy without a shirt. I run commando and luv the feeling.
There are a lot of concerts by my place and if there is enough traffic I run commando and shirtless. I don't know if women are honking and yelling at my body or my cockpiece but I don't care. I just love to show off...
There are only two sports I can indulge without firm support....otherwise there is severe discomfort and pain in my balls from being slapped by my heavy cock. Swimming and sex are the two exceptions.
