Am I bi a lesbian or a mess

Basically the long and short of it is I've been identifying as bi for the past couple of years but now I'm starting to realize that I might be a lesbian. I really only think of women when picturing anything sexual but in theory I can picture myself with a man. I don't have a vast dating history but of the men I was with I was never interested in them first, but when we did go on dates I wasn't uncomfortable, just uninterested. Part of me thinks that I just haven't meet the right guy, or I'm not as into women as a "real" lesbian would be. I'm not disgusted with men nor super interested but I'm not feeling butterflies with just any objectively hot girl.
