I don't have a lot of fetishes. But I'm just gonna come right out and say a serious fetish for nekomimi.
Despite being a (mostly) straight female.
Soft, sexy (anime) nekomimi (soft meaning, like soft ecchi, no bursting boobs, butt shots, or panty shots...nothing super inappropriate. Just a little sexy.
)
As for real life...not much really. There are things I'm attracted to more than others, but nothing I'd really call a fetish.
