Do YOU shave YOUR armpits? Or do you just walk around stinky?
People who shower regularly don't either. It was gauche to assume that the model stinks.
To be honest, I date back to when (some) women shaved their legs and maybe singed the hair off their forearms, but let the rest of it go wild. I never lacked for young tail when I was a young man and never found anything so offensive that it kept me from enjoying sex with my playmate.
