Is it normal That sometimes I don't want to be bi?

I just thought of something else, why do you have to put a label on what you are and just be yourself. You have already admitted to being Bi, I'd say you are 2/3 of the way there to being a lesbian. If you enjoy being with lesbians then just do it. When I used to meet a guy I was into I wouldn't say hello my name is Max I'm bi and I would like to know you better. Gay people are just people that have the same feelings that straight people have except switched and you don't have to put any label's on who or what you are or desire. If your feelings are changing and you are more lesbian than bi than just be a lesbian. You aren't lying to anyone, and you have a real desire to be with that wonderful woman and she more than likely doesn't care about anything except to get to know you better.
That's where lesbians and gay guy's are different, gay guy's can go to a gay bar and meet someone and 10 minutes later be in the bathroom having sex and then go home together and have sex all night long. And if it's Friday night have sex all weekend long and maybe become fiends for life or go each others ways.
