The question came up over at Steve Sailer's blog if Jewish women are more likely than other women to be lesbian. It wouldn't surprise me since data reported on this blog indicate that lesbians tend to be smarter than average, and they are more likely to come from wealthy homes. According to GSS data, here are the percentages of women by religion who say they are lesbian (sample size = 10,981):
No religion 4.0
*significantly less than the no religion group
No evidence here for more Jewish lesbians.
From what I hear, straight Jewish women are plenty good at denying men sex.
