I had an experience a few years ago that I want to share with your readers.
A close friend of mine, Steve, and I went fishing at a local lake, it was the middle of the week and there weren't very many people out on the lake. We both love to fish, but we hadn't been fishing together in sometime, so on this particular day, he called me up and wanted to know if I wanted to go fishing with him. There was no one at home, wife was at work and the kids were in school, it was the same for him. I told him, that I would love to go, and that it would take me a few minutes to get my fishing gear ready and that I would be ready when he got there.
When he got to my house I was not quite ready and invited Steve to come into the house while I finished getting ready. I told him I just had to find some shorts to wear and then I would be ready. Steve was wearing a pair of loose khaki shorts, T-shirt and sandals. I had a pair of shorts similar to his and decided I wanted to wear the same. As I was getting ready Steve followed me around the house; we were talking about fishing, wives and work. Steve being a man I didn't think anything about changing in front of him, so I took off my jogging shorts and started to put on my khaki shorts. I looked up and Steve was staring at my cock, I didn't think anything about that either, as a lot of men look at other men, just to compare. When he saw that I was noticed him staring, he kind of blushed and said " I see you don't wear underwear under your shorts either" I told him that I rarely wear underwear when I go fishing. It being a hot summer day I told him that I needed the extra ventilation. He laughed and told me he didn't wear underwear under his shorts either and as he said this, he pulled the leg of his shorts up and exposed his half hard cock, which by the way was about 7 inches. He said that it felt good when the wind blew under his shorts and cooled his balls off. We both laughed and started out the door to go fishing.
While we drove to the marina I couldn't help but glance toward his shorts every now and then, while we talked. I looked over at him once and the head of his cock was barely poking out of his shorts, this excited me and I am straight. I started laughing and told him that his horse was trying to get out of the coral. He looked down and pushed the head back inside, I told him I had the same problem with these shorts. We both kind of chuckled and I told him see, as I pointed down at my shorts, and there was the head of my cock poking out. And on the tip was a small drop of pre-cum.
I noticed that our cocks were similar in size and girth, except that he was cut and I wasn't. He is semi hairy and I am not. My balls are fairly nice size with little hair on them and his balls were about the same size and a little more hairy. We both were in good physical shape, I worked out with weights and ran a good bit, where as Steve just ran and did a little cardiovascular workout only. We both had slightly graying hair; we were both only in our late 30's.
