My secret is a little different. I am not zoo so I don't have to hide that, however I do hang out with several zoos, so I do have to hide that from my non zoo friends. To date, I do not have any non zoo friends that know that I have zoo friends, and honestly, I don't even think most of my non zoo friends even know what a zoo. They hear zoo and think it is a place to go to see animals.
As well, I have to hide the videos I have made. Even though they were originally made as educational videos, most non zoos are going to look at a video of an open ended av, showing the end of a stallion's penis as he ejaculates and flip out. TO me it is just part of the world of horse breeding and doing clean out collections on a stallion as well as showing the mechanics of how a stallion ejaculates, but to the average non zoo in a non horse breeding background (and often times even with a horse breeding background), it is just SOOOO WRONG to video a stallion ejaculating.
"I mean why does anyone need to know that?" is the thought train of most non zoos, even horse breeders. They let their bible get in their way of understanding of simple body mechanics when it comes to anything to do with sex. Pethetic really.
But yeah, non of my non zoo friends know of the "graphic" (to them) videos I have made for both education and my zoo audience, and they do not know I associate with zoos.
