I am currently a mentor and previously a judge and volunteer for many years at regional events. In all my years I have never seen anything remotely like sexual objectification. I obviously can't know your experience but I would be very very surprised to find this occurring... especially at competitions.
I believe this implication goes against core values of the org and certainly it's local volunteers. I have no skin here except to defend a program that is doing amazing work. My kids are participants and I have contributed to the org for more than 10y.
Just offering some more anecdata for passers-by.
