How do I Initiate a Sexting Convo and be a Dom

I have found myself testing the waters with a new sexual partner. I want to be able to take initiative more and I’m not sure how to go about that. I’m a sub, however I really want to be able to Dom. I know I have the capability, but im just nit sure what to do.

EDIT:

For clarity my partner is also a a female sub and this is a long distance thing. Like states away
