I'm not really ashamed of it. I grew up catholic so shame was something I really had to learn to overcome. Now that I'm atheist, I've finally learned to love and accept myself for who I am.
My wife knows I make AFV, she kind of helped me story wise with the very first release of the game. We've always been really open with each other about porn and our kinks. She's stayed mostly cool with the fact that I do this in my free time. There's only been a few arguments about it, and the arguments were mostly about her worries that certain people could possibly find out. Nobody else knows of course. Kind of like you wouldn't tell your kids, or the parents of your kids friends that you really like anal porn, I don't really want to advertise that I make a porn game to all the judgey Karens in my neighborhood, and not because I care what they would think of me, it's more that my wife and kids would be the ones to feel the consequences of that becoming public knowledge.
