You may still grow a bit in length, my penis stopped growing when I was about 18, and I’ve heard of guys still growing at 20. As you get to the end of puberty, the rate of growth slows down, so it’s difficult to notice when it actually stops growing.
You may increase in girth, as this usually happens later than the increase in length.
80% of adult penises, when fully erect, are between 5 and 6.5 inches in length, and between 4.5 and 5.5 inches in girth, so if you’re in those ranges, don’t worry about it, just learn to use it properly.
Hope this helps.
