First time Yixing teapot question

Hi! I ordered a Yixing teapot because the idea of a seasoned teapot fascinated me and I keep reading to only use one kind of tea with them. Does that mean oolong vs green vs black or oolong with dessert notes vs oolong with earthy notes or "this teapot is for Iron Goddess of Mercy oolong and only Iron Goddess of Mercy oolong"? Probably an obvious question, but I haven't been able to find the answer. Thank you from a tea noob!
