Usually length comes first and you thicken as you complete puberty.
Some people get an odd idea of what the girth should be - it's possible yours isn't small at all. But in any case it often happens that girth is a bit behind length when you are going through your puberty growth spurt, and girth can keep growing after length has stopped. This isn't guaranteed, of course.
