I definitely sympathize. I think I tend to feel like I have to sell myself as this perfect person -- who's totally knowledgeable and witty and sure of herself and has all the right answers and knows exactly how to re/act and everything -- and I'm allowed to let my imperfections (or even just the parts of my personality/life that are less likely to be socially acceptable, whatever that might mean in any given context) show once someone already likes me and will then be more inclined to let those things slide.
