While pleasuring your guy’s penis with your hand or mouth, ask him to rate his level of arousal on a scale of 1 to 10 (with 10 being an orgasm).  The idea is that you will bring your guy to several peaks and then back down again without climaxing.  For example, take him quickly up to a 7 or 8 and then back off and bring him back down to a 4.  Then take a short breather and just when he thinks he’s going to lose his mind, go in for the close.  Now take him up to an 8, back to a 6 and then all the way.  Take your guy on a roller coaster ride of pleasure!
