Missionary sex

I have come to accept: missionary sex is my(F) favorite, and somehow I feel bad about that. It’s what feels best to me physically, turns me on the most, is the only PIV position I’ll actually cum in, so I enjoy it every time (even if I don’t reach orgasm). And yet I feel like it’s accepted that it’s universally boring and too vanilla for guys. Like there has to be more performance involved. They’ll still get off, sometimes very quickly, so it must feel good…but it never seems to be their preference. Why is that? I’m always ready and willing to do any other position too, and other positions feel good to me also — but not as good as missionary. And feeling alone in that preference with partners can get in my head, like I’m not doing enough and they’ll find me boring, until they get to the good stuff they’d prefer. Is this just a mismatch/me issue I’ll have to accept and work around?
