i discovered this method recently and i've tried it twice. each time i hit "that" spot i feel the need to urinate. if i keep going, i'll eventually piss all over the place but it will still feel pretty good. i've heard you're sposed to be able to fully ejaculate and have an orgasm from prostate stimulation. what am i doing wrong? i can get lots of precum but no real orgasm or ejaculation of sperm.
