While there are theories that attempt to argue for an objectivity of aesthetic preference, I think it's typically agreeable that most aesthetic considerations are subjective and variable. We might be willing to speculate that symmetry has an objective aesthetic status. But it's not totally clear. And something like preferring vanilla over chocolate flavors of ice cream would be much more difficult to explain in that way.
I tend to see sexual attraction as similar in form to that type of highly variable and subjective aesthetic sense. Some people find protruding ears attractive. Others find it unappealing, others neutral. Nobody is clearly "right" about the status of prominent ears, so we chalk it up to personal preference. While there is a factor of cultural standards shaping preferences, and that is very much at play with physique, my view is that the cultural values are modifying a preference that at base is rather individualized.
is there any possibility a gay man would like a fat guy. because as far as i know, all gay men LOVE athletic guys with big dicks etc. as much muscle as possible, right?
There are some who prefer "as much muscle as possible", yes.
I actually think it's more common to prefer a guy who is toned and highly fit, than one who is bulky.
As for myself, I often find myself liking guys who are a little on the chunky side. Certainly I prefer that over body builders. A big mass of muscle is not appealing for me.
anyway, i remember walking in downtown at one point and this obese individual, not just fat, but HUGE! so he walked past this gay guy, and the gay guy just went "UGH" in complete disgust, very openly, showing disgruntled look. i thought that was so rude! i sure hope not everyone reacts the same way :/
No. But mentioning this seems to conflate the matters of basic human respect and sexual attraction. One
can see an obese person as human and deserving of respect without being able to find their physique sexually appealing.
I'll admit that it's probably uncommon for someone to be sexually attracted to a man who is grossly overweight (assuming that's what you mean by "fat"). I think that applies to hetero/bi women too, though. This does not necessarily entail, however:
1) A lack of respect for obese persons
2) No interest ever in anyone who is at all overweight
3) A preference for guys who are jacked/ripped
There is a vast range between obese and jacked like a body builder. Those are what I would describe as physiques on extremes, the former being an extreme of fatness / overweightness, and the latter being an extreme of muscularity.
