My T levels were actually monstrously high pre-HRT, and although I started growing pubic hair around age 8 or 9 I developed slowly and had my first ejaculation and first facial hairs at a normal age. My voice never deepened all the way so that although my singing voice is a low tenor-baritone, my speaking voice is still decidedly in a feminine range (one of my best attributes).
Instead of a neat little hole in the tip, I have sort of a wide 1/2" long slit from about where you'd expect the opening to be that continues all the way to just above the bottom edge of the corona, and I have to prop open that slit to be able to see the urethral opening which is way down low.
Looking around at photos, I definitely have Type I (glanular) hypospadia.
I hadn't really thought about that being related to my transsexuality before but now that you mention it, that's really interesting.
I hope this won't hurt my chances of getting surgery.
