I'm Jewish -those of us who were raised traditionally are usually taught not to marry out. Girls have a bit more wiggle-room than guys on that, since we believe that religion is matrilineal -at least in Orthodox and Conservative (usually) Judaism. Reform Jews don't usually seem to care much one way or another -as long as any kids are raised aware of their heritage. Conservative Jews tend to be split. Orthodox Jews, depending on how Orthodox, won't necessarily consider less traditional Jews Jewish enough. It really depends on the person. Jewish guys work the same way as other guys, really. Being friendly and flirty is good -we traditionally appreciate family bonds and people who care about them, but that's really one of those things that's down to individual preference. I know some Jewish guys who've married black women -some of whom were themselves Jewish, others of whom were not.
