No, you are not a freak. What you are attracted to isn't necessarily porcelain; I doubt you'd be aroused by a 3D porcelain, and the same goes for most of the 'porcelain-lovers' on /a/. Animu porcelains share the same traits: cheerfulness, kindness; they are cute and adorable, something you want to hug and protect more than jam it in.
This means you still have standards and the ability to feel more than primal lust towards someone. Of course, this will horibly offend the HURR DURR I FUCK THEM BITCHES chavs and I R EMPOWERED WOMAN ARRRGHHH dykes, which have lately taken residence on /a/ in growing numbers. You are a better person than the rest, part of a dying kind; and no wonder, you will probably live alone for the rest of your days, since porcelains that still lived up to those standards have succumbed long ago to pop culture, but you can take pride in your values. This is what it really means to be a porcelain-lover.
