My penis size is about 4-4.5 in erect and about 3.75 in in girth, i have a bone x-ray age of 15, do you think it will still grow? Im 17, had type 1 diabetes 14 years,i had a high A1C when i was 12-13, but ts much much better now, however My endocrinologist said im a late bloomer, but idk, im highly active and in pretty good shape. My main question is if you think it will grow, this is making me worried about going to far with girls and any suggestions or info would be great :(
