You can actually marry a Jew girl and get away with it, but, she's got to chase after you first. Never let her know you're interested first. You can date her once she's made it plain what she wants.
If you do get serious and she wants to marry you, she'll hint and hint and hint and finally come out and say it. Of course, you beg off "Sweetie, I love you and I'm happy, but, I've got to prepare myself for the day you're going to dump me, because once your parents introduce you to a "nice Jewish boy" who you know is a geek, but he's tolerable, you're gone!". She'll protest and say how much she loves you and it doesn't matter if you're not Jewish, but, you must be firm. "Sweetie, I know, but, I'm not Jewish, your parents will always hate me, there's going to be conflict and you'll resent me for it. Just let me know when they find that "nice Jewish boy" who's really a geek but he's tolerable for you. I'll miss you, but, I know it can't happen."
If she's serious, she won't go away. Finally, you tell her "OK, but, the oral keeps up even after the wedding night. I get open arms, open mouth and open legs on request. You don't have "headaches". "Not now, dear....." isn't in your vocabulary. Do you get my drift?"
"Oh, so you're profiling me, you think all Jewish....."
Hand up "Look, sweetie, I love you, yes I do, but, I'm not going down that road...."
She'll get mad, stomp off and her parents will be overjoyed. What they won't like is she spends a lot of time "mourning" you and won't meet any of those "nice Jewish boys" they've looked up for her. Finally, besotted and contrite, she comes back. She gives you a weekend fuckfest and sucks you dry and tells you how much she missed the taste of your cum and you don't consider her "unclean" when Her Monthly Visitor shows up. So you pull out the last stop.
"I'm going to record this and keep it, in case you forget". Then you ask her the questions. "Is it open arms, open legs, open mouth on request?" "You're not going to get headaches, right?"......you ask them all, record them, then make her say it to you positively. You email it to yourself and to a couple of your troll email addys. This is in case she decides to delete it from your computer or main email inbox.
It worked for me. I married my Jewish GF. I'm Catholic. We're happy. Only once did she try "not now, dear......". I got up to go for my phone and she figured it out quick. Off came the covers, off came her mightgown and she opened her arms, legs and mouth.
So you can do it, just be patient and prepared for her not to agree and dump you.
