In situations where nudity does occur with my male friends, and I'm straight, by the way, I get very self conscious because of the obvious difference. In those cases I wish I had less down there. Sometimes a big deal is made, sometimes a comment, sometimes a snide remark. It's almost like going to school with a zit on the end of your nose. Everybody sees it and internalizes a judgment.
I'm not necessarily proud of this accident of genetics, I mean, it's not like I worked out to achieve what I have. I think if I was buff I could probably accept a compliment better. In fact, I graciously accept and acknowledge compliments about my musical ability because something that I've spent my entire life trying to perfect.
A big dick is just that, and it's only good for one thing. And in my case it's not for bragging to my buddies about.
