well it helps to get "warmed up", maybe some cuddling with your partner, or some sexual play, maybe anal teasing, talking dirty, being sensual, for about 10-25 minutes, become very sexual aroused, maybe try masturbating a little while, but do it very little, ver strokes here and there, then when your ready, use a vibrator or stimulatorr, or if your using your partner or your own finger, (which using your own finger its hard as hell to reach by yourself, but just goin right into gives you substancially les pleasure, the prostate holds the seminal fluid, so let it build, the morwe th better, the longer you go the better.
but when you are "milking" try to touch it and stroke it as you noramelly would
hope it helps
