When you have a session with the goal of reaching a p-gasm, what would you say is the "order of operations" if you will...

Is it all mental stimulation? Is it a combination of mental, and physical stimulation through things like kegels, or direct stimulation of your prostate via massaging, toys, etc...?

I understand everyone is different, and practice makes perfect, but surely there has to be some sort of general "surefire way" guide one could follow to eventually get what they're after! Right?

Like say I wanted to do a session with the end goal being a HFWO; Would I just use mental imagery for a while (perhaps porn helps?) and as I'm approaching the "point of no return" do I do light flexes of my PC muscle? Or if I didn't want to ejaculate, would I just keep it all mental and eventually have a prostate orgasm? Can I control it at all, or is it Random???

I've been enjoying the journey regardless, but I will say sometimes I do get bit disappointed when I have a lengthy session for nothing to actually happen, haha.

Thoughts/ suggestions?
