Looking for a Master to Teach Me

[The Novice]

My wife and I are new to the lifestyle. I'm looking for a Dom to mentor me online. We are taking things slow as we still exploring our basic limits. My biggest problem is I want to please her, so being a Dom is not in my nature, but I want to learn so I can give her what she wants. She enjoys being tied up or restrained and being spanked. I have found that I love spanking her, and having my way with her while she's tied up.

First question, how do I over come my natural tendency to serve her?
