>>8700521It's a slippery slope and the main reason porn is degenerate. You start out jacking off to harmless stuff like anime cat girls sucking dicks but if you over indulge, you gain a tolerance to it and then feel compelled to up the dosage so you can get your rocks off. For some people, they just keep increasing the degeneracy until they wake up one day with a fursuit on the floor, a dildo in their ass, and a dead dog in their living room.
You can see this progression in pretty much any fetish, and it's actively encouraged by the porn sites to keep you hooked. It's like being a drug addict that needs more than a bump to get high, or an adrenaline junkie that has to keep doing more and more dangerous stunts. The problem with furries is, nobody ever told them to stop. At least, not until it was so late that they were fully committed. That's another problem with pornography, since it's private and personal, its really easy to go down the wrong path without anyone telling you to pull back until you really fuck up.
