I'm Guessing you are in a Sub/Dom relationship with you being sub, So what do you mean when you say "Master" Does he own you? Or is an unorthodox cute name? If he owns you how is that beneficial to your self esteem?
It’s important to remember that Master and I are boyfriends first, Dom/sub second. He does not own me, I am not a slave. We are equals.
His careful guidance and authoritative personality has helped me open up as a person. I trust and love him deeper than I have anyone. In exchange, he’s helped me love myself. My self esteem has never been better and he pushes me to reach my goals everyday. Some I had never considered until I met him.
