manshimajin,
I just had to say that not all Dominants are sadists, I for one find that the trust and willingness that a sub shows her Dom is the most important part of the life. Your lovely lady shows that to you.
Be the Dom that feels right to you and her, and never apologize for it.
I myself after 35 years as a Dom learned how to use a flogger to please my morgan, for me I never needed to use one or wanted too.
