No idea. Growing up, I thought their bare asses were kinda gross, like chimps. We had only one Saanen female, and I remember her just screaming her head off on occasion. Now I know she was just in heat and wanting some cock. I did try to finger her once but she wasn't interested at the time.
After that, I never gave goats much thought until after I fixated on deer, which are just much more difficult to find photos of, and to mix with. Their junk is very similar- even though deer are infinitely more attractive- I am a practical person after all and I'm sure a goat would be lovely. In some of the dairy breeds like Alpine and Oberhasli, some of the females are very deer-like too, so.
Cool part about the goat community is the (mostly female it seems) owners have this thing they like to do: Posting detailed and well-taken images of their goat girls' pussies onto goat groups asking the community whether they think they're pregnant. Also popular are very well-taken shots of dairy goats' udders, and butt shots of Boer goats (they have the nicest-looking pussies of all goats). In this way, I have found and collected easily thousands of photos of good-looking goat pussy. If you're curious to enter this rabbit hole, just image search "goat pooch" (some doofy owners like to call a goat vulva a "pooch" for whatever odd reason).
Maybe someday I'll have some goats for fun. They seem pretty entertaining and I bet the pussy is top shelf.
