Because do not permit it only once. There are men with an inferiority complex and a sense of shame because of "the premature ejaculation". There is the Slut which let the service mind that assumed the M Sei "which a protagonist wants to nominate the Koto which the partner expects" for origin be underlying. When I left the greedy male genitals which want to live many times with the woman whom "I want to give greed for protagonist shiio protagonist" to because "it is premature ejaculation", convert even the inferiority complex to the stimulation in the brain…! !And lead men to the new pleasure to feel to be a brain as well as the body, and raise it to the stage of feminine Ekusutashii "ejaculating in succession"; and Iku…! !
