Maintain the 2：8 principle of orgasm cruising altitude 

Sexologists believe that the pleasant sensation of male’s penis is strong and too concentrated, radiation range is small; By contrast, anal stimulation is not only strong, and pleasure radiation range is large, and easy to maintain, can bring the body greater euphoric pleasure feeling.

Based on the characteristics of male sexual pleasure, in order to let the body to enjoy a longer and wider orgasm euphoric feeling pleasant, in the take-off stage, need stronger stimulation, to activate the sexual sensitive nerve as soon as possible, this moment the stimulation of penis give priority to (80%), the stimulation of perineum and anal give auxiliary to (20%). After reach the cruising stage of orgasm, the body should focus on anal and perineal stimulation (80%) and reduce the stimulation on penis (20%), it help to keep a wide range of longer orgasm experiences.

In the cruising state, should master the 2:8 principle, that is to say, after entering the cruising stage of the orgasm plateau, the stimulation on penis should be reduced to about 20%, while the stimulation on anal and perineum should be increase to 80%.

According to the general research, anal pleasure (including prostatic pleasure), compared with penis pleasure, has a larger range, more satiety, and stronger sense of euphoria, which is easier to control and continue. Therefore, the development of pleasure during the climbing period is mainly focus on anal pleasure. But penis pleasure is also indispensable, that is to say, without penis pleasure, just like a train without its locomotive, the overall pleasure will be disappeared quickly, so penis pleasure is indispensable, and the perineum and anal function you can think of as a pleasure amplifier.

In general, during the cruising stage of orgasm plateau, penis occupy a small amount of stimulation and pleasure intensity (about 20%), while anal and perineum occupy a large amount of stimulation and pleasure intensity (about 80%).

Of course, different person have different proportion, this is a general principle only. Feel, try, grope, and adjust with your heart, then you'll get better.
