I am not into the toys or any objects, for that matter. (Your poll is heavy loaded on toy questions.)
But, there are guys in finance who take a rolled up Wall Street Journal inside their butt with no problem. Some animal rights activists cram live gerbils up their ass during working hours. (They say it's for transportation purposes only.) And I've heard tales of some manly men shoving 3 inch exact replicas of Trump's penis in between their butt cheeks.
I don't like what they do, but who are we to judge?
