As always, I end up suggesting that you give him something to help him understand. Otherwise you're stuck with a guy who has seen too many disney movies and thinks you want to be treated like a princess.
I think it is most important to let him understand how it makes you feel.
Think for example:
- You tell him you want to be spanked.
- That is all he knows.
His actions are going to be too predictable, unimaginative, and you're going to end up with a Madame Bovary problem. So what can you do?
You need to express how it makes you feel. Perhaps give him a book that revolves around the life that you are looking for. Let him know what it means to you, and why.
It isn't good enough to just explain what you want, you have to elaborate a bit to help him. I know it's scary.. I have a hard time ever bringing up what I'm looking for in a relationship with a vanilla girl myself. (And I'm into whips and chains and the like, so be grateful you have a bit easier time explaining this than some of us) Just a note: you talked about you wanting sexism. I want you to be careful if you mention something like this with him. He may get the wrong idea of what this means and might start making jokes like: "You know what's funny? The 19th amendment." That is going to get annoying after a while, and not really what you're looking for. Explain things in detail. And remember to be patient. I'm hoping for the best with you two!
