This is only my opinion and varies from Dom to Dom but after talking to a lot off Doms , I have come to the conclusion that what i do a lot do as well . Remember D/s dynamic first and foremost is a relationship and how you enter into a relationship is how you should enter into a dynamic . You she treat her with respect , kindness and be transparent just like a vanilla relationship.
Learn there likes dislikes , favourite food , or colour , what the do on weekends, these things will turn a submissive to start to respect you . And that is important but don't stop there you have to keep her knowing you care for her and not a play toy you own , it's fine during play if not 24/7 but if you live with her then you have to talk about what will change but keep dynamic happening .
The biggest turn offs a Dom can do and believe the first two hours are very important to wether she is interested to keep talking to you or not . The biggest turn offs is to say send me naked pictures , I own you and you will do as I say . They want to know the man who will be Thier Dom not a nerd trying to enforce his power straight away . A lot off Doms think that submissives are not allowed to ask questions that makes not a submissive not try .
So guys think about what you want done that respects so much that you are in her head well before the dynamic or some that does not respect you but sorry subs saying this , mindless robots just going through what the is telling her .
