Masturbation instructors use handjobs to teach the correct way to masturbate to abnormal masturbators who are doing it wrong! For "instrument-dependent masturbation" using electric massagers, they use single finger handjobs! For "overload masturbation" where the male genitals are rubbed against the bed, they use slow handjobs! For "abnormal friction masturbation" where bloomers are used, they use saliva and love juice handjobs! Correct masturbation brings about miraculous mass ejaculation!
