First - Great job on the 180. Keep it up. She will be hesitant to believe those changes so keep it consistent and be patient. Keep your motives pure.. that you are loving her better and being a being RT by making those changes.
As for the topic of sex - boy that's a tough one.
So who is the dominant one in your relationship? Even if it's 50/50, there is always someone in a lesbian relationship who is more of the alpha. Is that you? or wife?
Not that it really matters as I think either way you can take the first step.
Remember - confidence is sexy. Deal with the fears of rejection and go for it. Know that her response (if negative) has absolutely NOTHING to do with you.. only where she is in her journey.
If there is anything I have learned this journey is how much I let my Ex's BS and her fears dictated my self-worth. I could have totally validated her fears without believing them.
You are awesome regardless of what your wife thinks. You are attractive regardless of what your wife thinks You are strong regardless of what your wife thinks.
Make them your truth. Believe them to your core... and I think the intimacy problem WILL change.
Step boldly
