Does it mean a woman is not good enough or there's something lacking in her when a man decides to keep it "casual"?

For context, im in my late 20s looking for a man who wants something serious with me and eventually settle down. I have no history of physical relationship with men (by choice) and so far the men I have interacted with were more into keeping it"casual" with me which made me think does mean I am not good enough? Or there's something lacking in me?
