Hey! I'm going through the same thing right now! My girlfriend herself was more into a softer, more submissive vibe in the relationship, and it hasn't hurt our relationship at all. The opposite is true. Have you asked her how she feels about it and if she's okay with you taking the lead? If you're really bothered by this, check out the article on soulmatcher about

The most important thing is that you're thinking about it. A lot of couples figure out pretty quickly that one's got a bit more of a dominant vibe, while the other's more chill and flexible.
