Te isn't aesthetic, it's objective. Your Fi as an INTJ is probably telling you that it's ugly, because you value things being stream-lined or something.
And even people who think they are objective have subjective standards when it comes to sexual attraction, for example some men like curvy women and some men like women who are very thin, the former group finding slender women boring or not as sexy, the latter men thinking the curvy women are too fat or something.
That I think has a lot to do with culture, and also childhood things, because I have a firm belief that fetish begins in childhood.
Because how else do you explain people who are attracted to a broader array of types of women or men?
Objectively, Te would actually tell you that curvy or slender, large or small breasted, the best looking women are simply symmetrical, young enough to be fertile (or can mimic this youth), and healthy.
There's actually wide range of decent looking people, objectively speaking. Which ones you prefer sexually or find more striking is a matter of personal taste.
And that would be much more Fi than Te. Maybe even a little Se.
(Si types tend to be the pickiest, ime, and it's because they like what is familiar, like particular cultural constructs.)
