It's one of the genres that excites me more than anything. But I've been watching it for around 30 years now, and both new and good content is difficult to find. Especially in the recent culture of increased censorship around bestiality. When I first looked at it, I'd never seen it before, and I was instantly hooked. I could masturbate several times a day or even an hour to it, going on marathon-like binge sessions.
But the lack of new material inhibits me from getting as excited about it nearly as often as it used to.
These days, I masturbate every day or two, but it's certainly not exclusively to animal porn.
