From the guys point of view... I have never hid my CD and I don't feel like I have ever been discriminated against or had anyone run away from me. I have made friends over the years that have come and gone but that was not from CD. I have never had a woman turn me away because of it either.
I do have to say though that I do at times feel weird because of the things I do with CD. I always have a bookbag with me with the "essentials". I feel naked without it and would be so much easier to have a "man purse" Yes it is weird to have someone to question why I go to the bathroom so much but I always feel....let them deal with it. I am ok with how I deal with my CD...if someone else can't deal with me...then I show them the door.......but I really haven't had to do that.
I think deep down, past all the superfical stuff, humans are caring and in the end will deal with the CD.
