Sounds very familiar. I got left way behind when everyone else started puberty, too. I just kept anxiously waiting. Odd thing for me was that my flaccid penis seemed kind of long well before puberty, and part of that was the fact that I am a shower, not a grower. And with my penis being very thin, the thinness probably made it seem even longer.
I started to get pubic hair a few months after I turned sixteen and noticed my penis growing longer, but still no real change in girth. Started ejaculating at about sixteen and a half, and mine, too was clear, turning white and more plentiful about seventeen. Did not start shaving until college and then maybe once a week. No pit hair until college, either. Full length of 6.5 by eighteen and girth topped out at less than 3.5 about age twenty-one. Kept expecting added girth in my twenties, but it never happened.
