Me and my gf are both bottoms, can our relationship still survive?

So this has become an issue overtime, I'm versatile and can either top or bottom, her as well, though clearly we both have a better preference for bottoming. It was never an issue, we have been together for 3 years, and our relationship is perfect, I love her and we both do everything we can for the betterment of our relationship. She is amazing, I want to marry her. Our relationship is compatible in every single aspect.

But I think there may be some sexual incompatibility between us, we can get past it, that's why we lasted for 3 years. Though recently I see that she has had a harder time cumming, and she expressed that my general disinterest in sex (not assexual, I just take meds) bothers her sometimes.

We have sex on average once a week since we dont live together, for reference.

Are there any tips?? I want to marry her and don't want this to be the cause of our relationship failing. And no, we are never opening our relationship, pls dont suggest that!!
