Wings are a "normal" thing in today's society. There are of course people who still don't accept them but for the most part people are okay with it. Wings determine a lot of a person. Wings tell how strong angel heritage runs through you (you could have 3 sets or maybe just 2), wings can tell how powerful you are, and wings can also tell who your soulmate is. Castiel saw how his adopted parents are together and he always wanted it. He couldn't wait for the right girl to come along. Well...it may be a little different from what he expected.
