do it once a year... the reason you don't feel like it now,
psychologists call "tolerance"
It is thus stupid for many people to be against masturbation.
Nature has devised a way where people will want to have sex with a
member of the opposite sex because of tolerance built up from
masturbating.
Gambler's make higher and higher bets until they destroy themselves
also because of tolerance. Therefore, don't gamble or at least be
aware of this phenomenon.
