I don't have a customize shape option in my photoshop CC. Why is this? The only shape I can do is rectangle.
You do have to press and hold down the mouse more than a few seconds to see the fly-out menu of other shapes, or use the shortcut shift-u.
If you have already done that. Try resetting the Shape tool. Select it, and in the option bar, right or ctrl-click (Mac) on the icon, choose Reset Tool.
