More "simple psychology" for you: Zoo should not be a "mental weight" while you're still doing it.
If it's a mental weight for YOU, then you'd better stop doing it.
Well, sexual deviancy especially if it comes in the form of a social taboo on this scale can be difficult for a lot of people. And you can't just "stop being zoo".
Same as you can't just stop being gay.
Being gay is mostly accepted though. Being zoo is on the same level as being a pedo for an assload of people. Or a rapist.
