OK, so you are saying you love her very much. How much? You identify yourself as an anal-sex fetishist, and she has a history of anal rape. This is pretty much the picture of two people who won't have a successful long-term relationship (let alone create a good, solid family setting into which to bring kids) unless
- you try to stop being an anal-sex fetishist and
- she do some work with a therapist to try to bring closure on her victimization.
If you won't try to change, don't try to change her. You don't have the right. No matter how many flaws you can point to in her, it sounds like she was mostly a victim. She needs sympathy and assistance and protection, not sexual pressure from you who should be her main support in life.
I don't think you are sexually compatible. If you are highly interested in anal sex and are with a partner that doesn't enjoy it (which many women don't, and that is okay)--- you need to be with a woman that also likes it. This isn't your girl. She shouldn't feel less than, pressured to do things she doesn't like, etc. to please you. Because that is not sexual compatibility.
You say you are an addict with a fetish. do you see a therapist for this? I would consider doing this. They might help you sort through next steps. but I don't think enticing her to like it more to fulfil your addiction/fetish is the answer here. good luck
I'd say she used to be basically used for men's gratification (when she was a stripper) and now, if she is not into this sexual activity and you are pressuring her for it and even bribing her for it, she is being used again. Perhaps that is the nature of her disinterest. You sound like the anal sex and the domination and all, is more important to you than her autonomy. Perhaps she is beginning to feel like you are degrading her.
If this is a very important aspect of sex to you that you feel you can't live without, you might seriously consider moving on to find someone who wishes to be in such a relationship. When two people in a couple basically disagree on something one person feels is very important and the other doesn't not want, it sometimes can't be solved.
Certainly you should not be planning to have kids unless it is resolved, and you sound very, very far apart.
