You make good points on the whole sexuality aspect, I can admit when I'm wrong. I mainly wanted to express my distaste. Regardless,
Who the fuck would choose this life?
Like I said, I don't believe you chose it, but you can choose to act on it. If you're attracted to humans and animals, stick with humans. If you're attracted to simply animals, that sucks, but can you not just live a life without sex? I know if I was a pedo or into bestiality I would simply remove sex as an element of my life. I know I could do it, it's not that hard.
You say attraction to anthro is "obviously" related to zoophillia, but all the people I've talked to that like yiff happen to disagree. Is your one opinion enough to make me believe this is in some way zoophillia? I doubt it.
I'll tell you why I'm drawn to it, but you're not going to be able to use these reasons against me.
I like the colour, actually. It's a big thing, human porn has a severe lack of colour.
It's the only porn that I can fap to both male or female. It opens up so much more, as I don't really have to avoid anything other than feral and cub
The way it is drawn allows artists to make the perfect scene, unlike in real porn. They can stage it the way they want, show emotions the way they want, and add little things that make it all a much better picture
It's a break for regular porn. The same old same old gets boring after awhile.
The humanoid shapes. This part is essential, without there is no attraction. I also generally stay away from the more animal-esque yiffs. Example, horse yiff usually focuses on the horse cock a little too much, birds have beaks, ect. I only really like the dog yiff because it's closest to human. Why I like yiff in particular and not something like hentai? Probably a collaberation of the reasons above and the fact that I don't like the anime style and usually it's pictures of little girls.
