One would think that I don't know how to measure or something, but my education is in architecture/engineering. Trust me, I know how to read a ruler. lol... There were times when my exwife would suggest that I felt 'bigger', but when you're with the same girl for 7 years, shit happens. It wasn't until this other girl, who I had been with a short while when I was 23, and was then with again when I was 29 that I discovered that my dick had apparently grown. (my exwife and I broke up for a bit when we were dating, I dated this other girl for a bit, and then got back with the exwife and we got married)... On an aside, I actually went all the way to the age of 32, having slept with only 3 women my entire life.
I also got much hairier during the same period... Like when I was 22, I couldn't really grow a 'full beard', had no hair on my stomach, and not a whole lot on my arms and chest. That's simply not the case now, as I'm quite hairy. (there are of course pictures from the beach and stuff that show this quite clearly). But I didn't grow any taller, I was pretty much done with that when I was 18-19. (I'm 6'4")
I posted about this before, in response to a thread where a handful of others reported similar experiences.
