My first reaction was to say, what's the matter? I mean I see where you have concerns but dude, not every guy is hairy. My bro is about 30 years old now and I still don't think he could grow a full beard if you paid him. If your parents weren't hairy, I doubt you'll ever be. That really doesn't have anything to do with T levels.
And your penis sounds normal to me. I'm not sure you realize but the average male penis can't be slung over one's shoulder. Average size erect is 6". Yeah I know, still may not make you feel the best, but the world isn't full of 10" monsters (those wankers).
As far as the testicles go, that's normal too. Its common for one to be lower than the other or even one to be larger than another. Next you'll get paranoid that you're penis points a direction. Guess what? Most men's do.
You're still really tall. I think if you were lacking hormones, you'd be 2 feet tall. You just may not look exactly how you feel you ought.
Overall though, STILL GO TO THE DOCTOR. While they aren't anything to be overly concerned about (like lumps), its best to check to see if there is a larger issue. Perhaps I'm totally wrong, which wouldn't be the first time. But you certainly aren't a mutant if everything checks out ok.
