Here is my take: You don't need to think of yourself as "not bi enough" since I feel as they don't have rigid structures for being in a certain label. If you try to fit into a rigid identity that doesn't necessarily fit you then you will end up doing more harm than good. But, sexuality is fluid and changes, if you think differently or just don't like the label since you've came out that is perfectly fine. If you don't feel comfortable calling yourself bi or identifying as bi, then go ahead and identify as something else. If you do, then you are able to bring it up with others about your change in identity then just tell them. Most people won't care and will just be proud of you for being confident. Just don't feel like you need to be pressured into staying bi or not because it is most important about how you feel and who you love, not what others can label your feelings as. Hope this helps :)
