Could just be you've reached a saturation point of sorts, and just need to take a break from it?
Myself, I was buying them VHS's previously mentioned above, DVD's later and on line clips, then started hiring models to tickle the daylights out of, all good fun, but after so many years, the thrill seemed to evaporate a bit. Granted, I still think about it, just not acting on it anymore. I scratched the itch sort to say. If it will come back, who knows, but in the meantime, I'll just go with the flow.
PS. Ya, what is this nylon period we're going through right now? Nylon people seem to be in the minority, but they sure seem to be the loudest.
