The Masturbation Instructor corrects people who masturbate using improper techniques. For "device-dependent masturbation" involving vibrators, single-finger handjob is most effective. For "overload masturbation" where the penis is rubbed against the bed, slow, gentle handjob movements work best. For "abnormal friction masturbation" performed using bloomers, handjob using saliva and female lubrication is recommended. By learning the correct way to masturbate, miraculous massive ejaculation can be achieved.
