Nope, that's not all that unusual at all. Many transpeople don't get "bottom surgery" for a variety of reasons. I'm planning not to.
It's just a personal preference, and how your dysphoria manifests itself, though some transpersons don't have the surgery because it's expensive.
Everyone's different. Even though we are all not "normal" because we are trans, each of us is still going to be different. Just remember, gender is a spectrum, not a choice between two extremes. It's perfectly alright to be somewhere in the middle, or towards the middle but leaning to one side. 🙂
