I used to go running with a male friend and when we stopped I often noticed that he seemed to be semi-hard in his running shorts. He was together with a friend of mine so of course nothing ever happened, but I often wondered what it would have been like to sneak into the bushes, get down on my knees and "service" him. I was never sure if he had thoughts of his own.
if that is you in your profile photos, i am sure he did...if not he is blind.
