These threads are stupid (not that they were intended as anything else but mild entertainment to begin with; but they do become stupid) - as they always spiral down in stupid arguments such as: "So you like boys, I gather, yeah?" or "I bang only tens, bro." (always a white-belt, for some odd reason).
People have no problem accepting differences in tastes when it comes to food, yet, at same time, don't find it stupid to argue over taste in women. (At least with food, you may be a Ramsay, a Bocuse, and have a few Michelin stars to show for it; with most, we'd need to suspend disbelief and accept we're conversing with the second coming of Casanova and not some Cheeto-dusted fingered incel.)
At least with food - excuse me - but I think you have less (from the less important to the more, IMHO - I insist on "H"):
a) genetic influence on what you find "attractive";
b) influence due to whatever food gave you first (well, your taste buds) a stiffy (doesn't necessarily shape your ongoing preferences);
c) media-induced preferences: doesn't constantly try to override/supplant your love for Grandma's apple pie, and no apple pie has been subject to an ideal image changing like, I don't know, every decade;
d) influence like high-speed, available on demand virtually free porn (and this is the major one IMO): newsflash, your brain is plastic and your (escalating, in many cases) porn consumption will influence your taste.
Best thing you can do, boyos, is lay off the porn. 6 months later, you will thank yourself.
Over & out.
