It is fact but one of the most difficult to achieve of all sexual feats. A good friend told me the trick. By maintaining total concentration just prior to ejaculation and making the monumental effort to stay in the "moment" of ejaculatory feeling for as long as possible, the feeling of release can be maintained, though pumping has to be kept up, for as long as you can manage. There is always the overwhelming desire to relax totally after the initial squirting ceases but it need not be this way. I have maintained that sensation of ethereal bliss for 15 to 30 minutes only a very times. The sex partner gets almost nothing from this extention of orgasm from you so don't expect much cooperation.
