When is it time?

So, we've been on this road of forgiveness, self discovery, building of trust for 95 days. Yes, I'm counting days. I've told her, and I believe, shown her how important she is to me, and how much I appreciate her. She said that she doesn't tell me enough, and I asked her to make a conscious effort, along with me, to tell each other more often. She accepted.
So my question to myself is, now that I've recommitted myself to her and the family, realigned my priorities, and made things I hope somewhat clear, when is it time to ask her to start looking at what I need from her and make an effort to show those expressions of love to me?
I think that most people, including her, would automatically think "sex", and that's fair. I'm a guy, and most guys need that the most. I'm not saying that it's not important to me and that I don't need that, but I've learned to redefine what I need as opposed to what I want. And surprisingly to me, that's not what I want or need the most.  What I want and need is for someone to acknowledge, even ever to slightly, the things I do for them. Whether it's big or small, it's nice to hear a "thank you, I appreciate what you do" every now and then, along with them returning that expression by doing things that take the burden off of me, again, big or small.
So, when do I ask? How do I ask? It's the little things that make the biggest impact, and I think it's an important step to seeing where and when this road will end.
