It really bothers me when people used the "depraved" word when it comes to sexual acts between consenting adults.
You know what's depraved? The glorification of war and killing. Not fucking. The cognitive dissonance some people get indoctrinated with is sad or scary, depending on how you look at it.
Like someone else mentioned, sexuality and psychology are incredibly complicated, and almost the majority? of media aimed at children involves anthro-characters.
People are heavily conditioned in many parts of the modern world to see violence as "exciting" and any mention of sex or intimacy as embarrassing - except when it's pseudo-violent like bros bragging about being real men because they "bang" so many chicks.
As for media, here's the thing - a reason why media geared towards children uses animals is because people - not just children - can identify with other creatures given human qualities. It's a basic premise of cartooning, and many other subjects.
But, society conditions people to feel ashamed at "childish" things, because the game is all about proving to the other monkeys how adult (and competitive) you are.
One thing that seems to trigger shit panic crisis in 20-somethings who can't get over having an (anthro) cow at "furries" is the notion that there's something unseemly and disturbing and just "wrong" about adults making use of what the onlooker sees as children's material. It's even worse among gamers because adult gamers "stay in touch with their inner child" by continuing to play games with what gamers call "mascot characters". I've said before, elsewhere, that gamers are insecure at the existence of furries because gamers like anthro characters too, because people in general just plain identify with such things (at some level, however small), and the gamers are upset that someone is doing something confusing and alien with something they (secretly) like and find identifiable.
Short: people are a bundle of issues but tend to believe they've got a pretty good grip on things, and they project their issues at anyone, or thing, that steps out of line with the perception of normative culture. Normative culture, meanwhile, is a shakey bundle of barely lashed together sticks; most folks spend their time with eyes squeezed shut muttering "I'm normal, it's okay, everything's normal."
