Susie, Darth Vegeta wasn't being hostile; he was literally curious about it, that's all. I have always found this community to be very tolerant, even of my more "unusual" fetishes.
Regarding your other point, technically, an attraction to specific body parts is called "partialism," an attraction to inanimate objects is "fetishism," and nonconventional erotic activities are "paraphilias." On the Internet, all are commonly lumped together under the term "fetishism," though I agree with you that they are different.
Very best regards,
