You know, a lot of people understand the word "fetish" to mean something it doesn't. What "fetish" actually means in sexology is a very strong, sexual/erotic attachment to an object, to the point it’s needed for arousal. What a fetish isn't is liking something or being turned on my something. That's just...well, liking or being turned on by something. Fetishes also are generally understood to be formed in early childhood, not later in life.
There's also no one thing everyone of any given age or gender or orientation finds arousing, like breasts. The media generally doesn't represent human sexuality accurately in any respect, and this is one of them. There's no "should" in what anyone finds arousing. There's just whatever we do or son't at a given time, okay?
Now, without you saying more than you have, I can't know if what we're talking about a fetish or not, but even if you have an actual fetish, it's not like that isn't okay. Fetishism is one possible expression of human sexuality, just like others.
How can I help you with this beyond those starting points?
