O Force 2 Help and Tips? (Male Vibrator)

Hi everyone. I've been using my O Force 2 for a few weeks now and it's great, but a lot of the reviews mention 'intense orgasms' while I've found my orgasms to be fairly normal. After this long I figured I might be using it wrong (lol), or I might be missing some sort of trick -- has anyone that has used it got any tips for better orgasms with this toy? Thanks!
