I have small wrists and I love them. It makes your forearms look bigger than they actually are. BB all about illusion. Having small joints makes your muscle bellies appear fuller. I also have small ankle joints which make my calves appear bigger.
It's the same with midsections. having a small waist makes your shoulder girth appear wider then if you had a wide midsection. Illusion.
So be thankful you have small joints.
