My husband has this fantasy

And it’s me coming onto him and being on top but doing it anal...but he wants me to initiate everything . I never did anal before him..in my opinion he is lucky we even do anal 😅. I’m sexually a shy person as I was raised super religious but I’ve opened up a lot with him ..toys and what not . I don’t even know how to fulfill this for him unless I’m drunk. And even then I don’t know./.also he keeps pressuring me to do it and I just had a baby 7 weeks ago...he’s lucky we are even having sex! But if I tell him that he scoffs at me and says that what women are supposed to do especially with my religion ...of course I disagree ...thoughts ?!
