I think so. It sure seems that way. The crooked pinkies (one is more than the other). Yes, I have a smaller than average head (I think it was size 7 at graduation, tall 5'11", skinny). Yes, testicles are small. My breast were never large, muscular yes. I had the learning disabilities and speech problems. I might even still have some speech / vocabulary problems. As for fertility, I am in my 40s, my wife is older than I am too... We haven't tried to get pregnant.
I am looking for that final link to why I wear diapers. I was hoping to find something in here very definite (such as bladder muscle or just general incontinent problems), but the only thing I came across was the shyness / passiveness and perhaps maybe me wanting to have this problem corrected back when I was 3/4/5 and not learning about it until now - hence me age regressing to 3/4/5 when it didn't matter how my words sounded.
