I have turmoil when it comes to that. I love it when I'm not the only one, but at the same time, I hate it. It's conflicting. I'm happy that there's someone out there who understands/is like me, but I'm upset that because there is someone else, I am no longer unique in that aspect.
Like finding out that I'm not the only shipper in the Wreck-it Ralph fandom of BradMora (Brad/Tamora). Or in the Mass Effect fandom, not the only (well, one of them) shipper of FemShep/Male Shepard as a pairing.
