This is a collection I've had for 13+ years, now. I never removed entries, so I rarely add to it.
In all that time, I still like all of them. Perhaps not as much as I did when I first added them, but I still do like them all.
My rules for this subset of my collection are that all images must reasonably fill a 1920x1080 screen (or pair it with another image such that they do together), and only softcore images are allowed (meant to be easy on the eyes, but not too distracting.)
