By the way, I just wanted to pop in and say one brief thing to kind of sum all this up which is to make clear that even the idea that there are "causes" for you having greater or more frequent desire than a partner is, itself, kind of a busted idea that probably comes from some misapprehensions or stereotypes.
For instance, often people think that people with penises and testes are "supposed" to want sex more than those who don't have those body parts, even though there's no physsiological basis for that belief. same goes for the common idea that people who have vulvas, vaginas and uteruses should desires sex less, or should only want it when men want it. That, too, doesn't have any real basis save that it comes from a lot of cultural biases and assigned roles and power dynamics around gender and sex.
This really is one of those things that differs in the same way that our hunger or thirst differs, that our desire for physical activity differs, that our interests differ, which is to say that people are diverse as hell, especially when it comes to something like sex that involves our bodies, our minds, our life histories, our current circumstances, our personalities, our interpersonal relationships and a whole array of other factors. <3
But please do know there's no one "right" level of desire, and that if you have the idea that couples somehow are supposed to automatically be matched in how much sex they want, when they want to be sexual, and all the ways they want to be sexual that that doesn't have any basis in reality. In reality, being with someone as a sexual partner is just about finding those times and places where and when our desires align, that's all, not about then always aligning.
