My suggestion would be turn it into a submissive role in your mind. Perform for her as a domme because it pleases her and it's what she wants. She will be doing the same for you since you said you're both switches. It's hard to assume a second role when it's not the one that comes most natural to you. Also if she seems to be handling it better on her turns being dominant then sit down and talk about it all together. Maybe she can show you how it is she's able to take control and if there's any specific practices,thoughts or considerations she's using to make it easier for her. All in all as long as you both are happy that's what's important.
