I needed a certain image to use as a reference, but I can’t seem to find it anywhere. It went like this:

It was a massive, green, demonic-looking horse cock that may or may not have had spikes. It was just that, the disembodied penis on a plain background. Really weird and strange, I know, bit if anyone could help me find it, I’d appreciate.
Thanks

I don't know about green, but this search gets a few horse dicks:
disembodied_penis equine_penis solo -anthro -feral

The annoying thing is that I'm sure I saw that post a while ago. Having done a few more searches I'm guessing it just has the "penis" tag, and not "disembodied_penis" which would make it really awkward to find. I'll keep looking for a bit though.

A quick edit:
It could have been deleted, how long ago was it that you saw it?
adding "status:deleted" to that search gives four results.
