OK Cupid survey: Jews masturbate the least

According to an OK Cupid survey of close to 80,000 subscribers, Jewish men and women masturbate the least, which I find easy to believe considering the supposed grave sin that comes (pun intended) upon those who cause themselves to waste seed, of course the women who answered the survey are probably lying, because it’s no sin for a woman to masturbate and therefore why wouldn’t they?
