Do you understand why she didn't like the IUD? It's important to understand her reasons. When you understand each other, it's easier to find solutions.

You've got to stop thinking of "nothing is up to me," or "this is up to her." It's up to BOTH of you. POJA doesn't allow one spouse to be in charge of the other. So, SF is not up to you. It's not up to her, either. It's up to both of you to find a way to make SF enjoyable for both of you.

Most things are not up to me because she just bulldozes me and I'm pretty easy going for the most part.
POJA, if followed, will protect you from being bulldozed over. It will also protect her.
