Except if it's almost anything else, you can fap around it, despite it or regardless of it. With feet it's still a sexy girl, she's just barefoot. Most people are fine with muscle even if it's not their fetish if She-Hulk's popularity is an indicator. Stuff like BDSM is still a hot girl, just tied up. Even if it's futa and you don't like dicks, you can fap to her tits and ass, or just squint a little and imagine it's a strap on. But with fatfaggotry, it's just an unappetizing tub of lard.
