Different guy, good sex life. Here's my advice.
Make sure there's nothing major stressing her out. Women hate that. Do things for her, make her feel loved and appreciated. Same idea: lots of physical affection that isn't about sex. Hug her. Kiss her. Smile at her. Compliment her. This kind of positive treatment should be normal in her mind.
That's the first part of preparing her to want sex. If you don't have this, she's not gonna feel positive enough for sex a lot of the time. So now she's feeling pretty lovey-dovey as a default. Now, make sure to show her that you think she's sexy - again, without demanding immediate sex. Touch her a little more suggestively. Outright grope her if she likes a little shock. Eye her up, and tell her you like what you see. Obviously choose your time and place: never when it would humiliate her, never when she's stressed or upset. Only when she's feeling fairly happy. If she's receptive, push forward to making out, but again, don't push to sex. This is great for times when full-on sex would be inconvenient, like you got some place to be and don't have even 10m or whatever.
The result of that is now she's thinking about sex. If you want sex, start stimulating her well in advance of a good opportunity. Get it on her mind. She'll get herself the rest of the way there. Then, when a good time comes, start it up again and keep on pushing. Unless it's something stupid like you guys staying out too late at a party and now she's falling asleep, you're gonna get some. And even then, if it doesn't work out, don't get frustrated. (Unless it never works out. Then you talk it out or break up.)
So that's the plan. Get her comfortable with you. Make her feel loved. Show her how you find her sexy, how you want her. Then she'll want sex with you. Even if she's not horny for herself, like she wants to cum, she's gonna be horny for you, like she wants you to cum. And the more you do it, the more she gets used to wanting you. Train her.
