It’s fairly obvious that many of us would say they do not like large fake boobs. And, as they age, they take on a round, hard unnatural shape.
My second objection would be to disproportionately large quads and gluts/butts. Popular with some but I just think it makes the physique look unbalanced.
I am with Scythian on these points.
Bloat abs can be a turn off depending on the girl but im a weirdo who gets off any anything outrageous minus beach ball boobs
For me it's arms. I love muscular bis and tris but when they're disproportionately large compared to the body I don't see that as attractive - whereas Lats, calves, glutes etc are even more attractive when they're disproportionately large Blakelee is a good example
