Query regarding prostate milking section in Aneros Wiki

So I was reading Aneros wiki and found a text there. Are they referring to refractory period here or is this something else?

“A man can learn to perform a self milking without orgasm by using his PC muscles to manipulate the Aneros massager, it should be noted part of the mechanism for orgasm for a male involves the accumulation of fluids within the prostate and associated ducts; accordingly once thoroughly milked, a male may be incapable of achieving an ejaculatory orgasm regardless of the degree of stimulation, for some time after. “

How to make sure the P-tab always touches the sweet spot?

I own an Aneros Helix Trident. I have a very receptive perenium. The distance between the main stem and the P tab is roughly around 2 inches while I feel that i feel most pleasure(sweet spot) around 0.25-0.75 inches from the butt hole. How do I ensure that the P tab always touches the sweet spot when the contractions begin. I don’t want to burn/melt my toy.
