I actually have the opposite opinion! I get really sad when people don't know who I am. I do like getting photographed. I do like people telling me I look like the character. I do like the attention. So not having anyone recognize me is a bit disheartening, considering I've spent all this time, effort and money.
(BTW, OP, you should totally cosplay that! Coming from a Kid Flash fan, and knowing that a lot of people watch Young Justice now, I'm sure a lot of people will recognize the fact it's a Kid Flash, even though they might not know which Kid Flash.)
