I agree with what Arch and denu have said.

Speaking from personal experience, I identified myself as a switch for most of my kinky aware life. Now, I'm a submissive.
I found myself not being fulfilled with asserting myself over my partner and take control, so I bottomed more and more often.
This happened, as change is natural in a person's life. Maybe what you're experiencing is a settling of your nature and not fighting it might give you a sense of rightness that I personally recommend.

When I was going through that change, I got a bit anxious. I started to think that I'd "loose" myself in some way or that my outside life would be affected by it. None of these things happened.

So far I've found that this rightness I speak of is a great source of joy for me.

best regards.
