Maybe she has no feedback because no one wants to see a girl with hairy armpits
Hairy armpits can be really horny on a sexy girl. Back in the 70s nearly all women had hairy armpits. The fact that men now find it vomit-inducing has more to do with the unconscious urges people have to conform with the standard to fit in.
It's the same with body size. Back in the day, healthy food was scarce and only the rich could afford to be fat, plump women were lusted after and slim women were the vomit-inducers.
