Best suggestion, go look up the Manosphere.
Roissy would be the best start. Heartiste on Wordpress, I believe.
There are others, too - you won't worry too much about improving yourself (do that anyway), but focus on how to train her thoughts. The term you need is Game.
Learn to game her, keep from being abusive, but "power" her by working her mind. The techniques work (I learned from necessity, not to pull women, but to deal with an aggressive woman I couldn't get rid of.)
Techniques work; you'll want to tailor them to your needs.
Examples like Push-Pull - used to create attraction - are above- Dickles @ #2, for example. Push-Pull works there, too: If you want her to have sex with other men, say, while doing her doggie style, tell her you wish you could see her mouth wrapped around a man's dick at the same time. Ride her hard, don't let her come - and don't let yourself come, either. The thought was SO hot though....
Next time she shows interest, be disinterested. She can give oral, or suggest anything... Let it go.
Suggest to her you have an idea of how hot it would be, again... But you bought a suction-cup dildo for her to suck while she's taking you doggie style.
And Dickle's suggestion, too.... Gentle strokes for the Lady.... Until YOU come. If she does, OK, if not, oh well. Her need should fill in the blanks soon enough...
The other big deal is Compliance Tests, most of the rest of what people have been talking about - and meeting your "subtle" criteria. Tell her what to do, and make sure she's done it correctly and to your satisfaction. Praise her if so, show her attention, give her affection. IGNORE her attempts to get the same - if she ASKS you to do "X", ignore her. (Unless she's earned it above.) If she DEMANDS, withdraw: Leave the house if necessary, but make distance, IMMEDIATELY.
Pavlovian conditioning, Game, and positive reinpowerment. If you want to use negative reinpowerment, you can do that, too - make it a ritual. Don't use a dildo to punish her, if you also use it for play. You muddy the waters. If you spank her with a hairbrush, that's the punishment hairbrush, not her daily hairbrush. Make it a time, like 7 PM every Saturday, to review it. You could make it play first, using positive reinpowerment. Then bring in the negative. She did three of four tasks perfectly, you make note and praise her for them... But then make note of #4, and ask her if she had the time and ability to do it; if you were clear in your instructions. If she admits these (she may not at first), you can persuade her to accept punishment - maybe a "fun" spanking, and after that, some reward for the pain... As the ritual gets started, increase the pain, reduce the pleasure, but praise her for taking the pain, and making you proud of her... Etc.

Next, a quick guide would help - I'd suggest Miss Abernathy's guide, you can find it on Amazon.
Lastly, and MOST importantly - her presentation is a GIFT, and you MUST earn it, FULLY.
If you let her down, or betray her trust in any way, you're DONE. Don't expose her, make her feel unsafe, or give her any doubts. You must provide for her what she needs. That doesn't mean provide what she wants, or says she wants, of course, but give her the direction (meaning that literally, a direction in life); discipline; sense of self. You probably know that, but it ALWAYS bears repeating.
