dressing like a male man doesn't mean your are a mail man... but other may think you are.
that is a basic concept.
with cosplay its even worse because you become someones fantasy in real life. You are literally meshing fantasy with reality. Now through in sex with this...
that is why you should be cautious.
It was a really bad analogy and you should just drop it. Dressing up as Catwoman doesn't mean you are Catwoman, but others may think you are? Because something about meshing fantasy and reality? And that means you should expect to be groped? None of it makes sense.
