Most toys have dubious lenghts, plugs work only good if you can ride them sucked to a table and angle the egg to tease your prostate.
99% of prostate play is mindset.
I can look at porn but sometimes the idea or something gets me harder than usual. That is mindset.
You can prostate play all you want if you don't have the right mindest. Your prostate is most sensitive and hard and easy to tease when you are mentally into the idea of fucking someone or being fucked rn.
Just imagine some hot nurse is milking you off, put xl anal beads in, then when you are about to cum pull them out slow and steady. POUND, POUND, POUND.. really fucks the milk out of my nuts as I keep stroking.
The prostate should ADD to the overall experience, not be the only thing you use.
Of course the masochists here will disagree and say that draining with no pleasure through a cage feels best and just have it ooze out.
I get it, it's good, but just because you have a fetish for that.
