A lot of furries are intrigued by the mating behaviors of other species but are met with the Puritanical guilt of society. There's something innately and intriguingly animalistic (by definition I guess) about how other creatures breed , and there's a romanticism in being knotted together if you're a dog. I've heard other people have the adjacent sentiments about cats in that there can be multiple males contributing to the litter. People find and live out niche kink ideas from everything. Some people want to kinkshame, and there are a lot in the furry community, though they tend to be the early 20's uncomfortable-with-themselves folk.

But I just jerk off to gross femdom porn.
