LGBT: does anyone else feel this way, and how do I get over it?

I know that I am gay, I have known for a while now, and I feel comfortable with myself, and I plan on coming out soon. but for some reason, I feel embarrassed when I say something out loud to myself, when I say something about getting a boyfriend. or I guess typing it, because I just felt it there to. it's not a bad kind of embarrassed, it's more of somehow happy/excited, but uncomfortable. I also feel this whenever I think about just being openly gay in public. so far it's just been thinking about it, because Well, I'm not openly gay yet. (as I said earlier, I plan on coming out soon.) will this feeling just gradually go away, as I get used to it? and are there any other people who get this feeling as well?
