HELP! I 18F am not sexually pleased with my partner 18F What do I do?

I have a fiancee; let’s just call her “wife” to make it simple. When me and my wife met, we both knew that we were very sexual people and that we had wants and needs like a normal couple. We waited about 8 months before we did anything to each other to just make sure that we were sure, as it was our first time physically doing anything sexual with another person. For about a year and some months now, we have been very pleased in bed. Let me just clarify that I and my wife are both Switches. Yes, I have seen that she is leaning into being a sub more than a dom, which I do not mind, but for the past months or so, she has become a full sub. I of course want to please her, but I cannot always be a dom; the sub that is just lurking around wants to come out from time to time, and she cannot please that side of me. There have now been times when she has ignored my desire and need for such attention. I talked to her about it about a week ago. I asked her if she thinks she is fully a sub, and she told me she may just be so. I would not lie to you, but that broke me into shards, as from the first communication we had about our sexual preferences, she agreed on what we liked and what worked for both of us. I took time to think of how we could make this work, but nothing seemed to be a solution. I always want to please my wife to the best of my capabilities, so I did as she pleased while not caring for the side of me that was aching. She has told me that she is not a sub but a very heavlily sub with a little bit of dominance. I love her very deeply, so I want it to work. What can I do?
