What can i be doing better

So i have made some progress with the Aneros Helix Syn been using it on and off for the last 8 months or so. Recently I have had a warmth feeling when I contract my PC muscle and recently got to the feeling of pulsing/ waves from the prostate how ever that feeling doesnt last long.. But when i read online that say to contract and release how ever the only time I have had this feeling is when im
Holding the contraction tighter and tighter as long as i can and the feeling gets better. Should i continue with this method or just strictly follow the mutlple guides online.
