Same boat here. I think that everybody is bigger than I am. I was abused as a child so I remember seeing my perp and thinking he was huge! I guess that has always stuck with me, and has always made me feel inferrer in that area. I know I am not small (not big either ;o) but I am never comfortable being nude around other guys and always find myself comparing what I have. It sucks and I hate the facts that I can't be comfortable in my own skin. It has made me a pretty private person and I have even found myself trying to hide my naked body from my wife. I also have been wanting to join a gym for many years but never have because I am to afraid to be seen. So basically understand where you are coming from and want ya to know you are not alone in those thoughts.
