I think hot/un-hot is in the eye of the beholder and not a "set" thing. I might find the guy pleasant looking.
So, I'd say, yes, there is a bit of superficial about what you want; my husband is fat and bald and was when I married him and actuallly grew his eyebrows closer together for awhile because I love unibrows!

but it is what
you want and you are allowed to what whatever you want!
But it also might be a mechanism to keep guys at a distance so you don't have to deal with the difficulties of a relationship on a serious level? You might want to look at that if you have a therapist or counselor to discuss that with.
